Медиатор в зонах обмена: искусство или свободная фантазия?
Authors: Воронина Наталья Николаевна ,   Lobachevsky State University Press
Published: January 2021

В статье обсуждается мнение А. М. Фейгельмана о посреднической роли произведений искусства в зонах обмена с точки зрения негативной диалектики Т. Адорно на примере сайнсарта. Автор обращает внимание на различие между произведениями искусства и фантазией. Затрагивается «вечный вопрос» о природе искусства и делается вывод, что посредническую функцию может выполнять не только искусство, но и фантазия. Сравнивается негативная диалектика Т. Адорно и фальсификационизм К. Поппера. Ставится вопрос о различии интерпретации сайнсарта как направления искусства или как направления свободной фантазии. Представления о науке и искусстве слишком неуловимы и вечно дискуссионны, поэтому в статье предлагается сузить тематику обсуждения и говорить лишь о таких элементах науки и искусства, как фантазия и познание. Это представляется более доступным для исследования того, что может сыграть роль посредника между наукой и обществом в «негалисоновских» зонах обмена.
Визуальные образы ученых и апгрейд социальных ценностей
Authors: Шибаршина Светлана Викторовна ,   Lobachevsky State University Press
Published: January 2021

В данной статье предпринимается попытка рассмотрения процесса формирования и развития ценностей (на основе концепции зон обмена) как в научнообразовательных, так и в культурных практиках, вовлекающих проблему ценностей и смыслов науки. Показывается, что в той или иной степени габитус науки осваивается в «гумбольдтовских» зонах обмена (например, университетах), что может являться почвой для дальнейшей адаптации когнитивных и социальных ценностей и смыслов науки как динамичной практики. Обосновывается идея о том, что помимо специальных научнообразовательных зон обмена вовлечение в научную деятельность происходит во многом посредством ценностей и смыслов, транслируемых через попкультуру. Исследование этого процесса включает описание и интерпретацию стереотипных образов ученых, создаваемых в научной фантастике, кино и телесериалах, в контексте проблемы социальных ценностей. Эмпирическим материалом послужили современные телесериалы «Флэш» и «Звездные врата». Помимо уже описанных стереотипных типажей ученых выявляются новые образы, связанные с новыми социальными и культурными контекстами и транслирующие новые социальные ценности и смыслы (апгрейд).
«Digital existence»
Authors: Касавина Надежда Александровна ,   Lobachevsky State University Press
Published: January 2021

В статье речь идет о динамике экзистенциальных условий существования человека в электронной культуре. Рассматриваются дискуссии экзистенциальной философии техники XX века, в центре которых – предостережение о дегуманизирующем влиянии технологического развития и массовой культуры на жизненный мир и экзистенциальный опыт человека. Для иллюстрации философских предостережений используются кинематографические образы «дискурса катастрофы» XX века, символизирующие кризис идентичности, искажение процессов самобытия, экзистенциальной коммуникации. Делается предположение, что цифровая культура снимает многие из обозначенных опасений, становясь необходимой платформой социального развития личности. Это осуществляется благодаря современным формам формирования идентичности, коммуникации и интеракции, широким возможностям личностного и профессионального роста, актуализации новых социокультурных практик. Эта позиция адресует к положительному вектору оценки технического развития, связанному с пересмотром схемы взаимодействия между человеком и техникой, преодолением утилитарного подхода к ней. Роль «экзистенциального измерения медиа» как направления социальногуманитарного познания, критического мышления, философской рефлексии проявляется в соизмерении достижений цифровой цивилизации и новых форм человеческой уязвимости и личностного раскрытия. Осмысление общих и частных случаев проявления экзистенциального модуса цифровизации обретает все большее многообразие, приближая к пониманию ее новых ресурсов и рисков для личностного пространства и жизненного мира, к реконструкции новых форм экзистенции в современной культуре.
Гражданская и профессиональная наука: случай Великого эксперимента по изучению приливов
Authors: Соколова Татьяна Дмитриевна ,   Lobachevsky State University Press
Published: January 2021

Статья посвящена анализу феномена гражданской науки и ее роли в процессе профессио-нализации научного познания на примере одного кейса – Великого эксперимента по изучению приливов 1835 г. В истории науки XIX век предстает веком научного прогресса, воплощенного в индустриализации и профессиона-лизации научного знания, новых открытий и изобретений. Количество научных дисциплин возрастает, активно развиваются новые тех-нологии, симбиоз науки и технологий приносит экономические плоды и радикально изменяет всю структуру общества. В то же время именно в этот период на фоне профессиона-лизации науки возникает явление гражданской науки – участие непрофессионалов в научных исследованиях. Анализ кейса великого эксперимента по изучению приливов показывает, что объяснение феномена гражданской науки исключительно экономическими факторами является неполным. Организация научных исследований в рамках гражданской науки повторяет внутренние конфликты научных институтов, связанные с иерархическим разделением дисциплин. Кроме того, гражданская наука закрепляет привилегированный статус профессиональных ученых по сравнению с добровольцами, так же как ранее представители «чистых» наук имели более высо-кий статус по сравнению с учеными, проводя-щими эмпирические исследования.
Индивидуальная перспектива и интерпретация
Authors: Куслий Петр Сергеевич ,   Lobachevsky State University Press
Published: January 2021

В предлагаемом обзоре рассматриваются современные дискуссии в области интерпретации так называемых предикатов личного вкуса. Эти выражения, как известно, оцениваются с учетом индивидуального вкуса: то, что один считает вкусным, другой таковым не считает. Их формальная семантическая интерпретация сталкивается с рядом технических проблем логической семантики, а также более общих философских проблем, связанных с пониманием того, в чем может заключаться природа разногласий о вкусах, того, какова структура пропозиционального содержания и т.д. Автор предлагает экспозицию ряда показательных подходов к решению проблемы семантики предикатов личного вкуса, а также собственный взгляд на некоторые сложные случаи в интерпретации этих предикатов в сообщениях о верованиях de re.
К дискуссии о легитимности эпистемического империализма в социальных науках
Authors: Тухватулина Лиана Анваровна ,   Lobachevsky State University Press
Published: January 2021

В данной статье осмысливаются некоторые вопросы легитимности эпистемического империализма как процесса, который характеризует специфику междисциплинарной кооперации в социальных науках. Данная проблема рассматривается на примере дискуссий о легитимности империализма в экономике. Автор анализирует основания расширения сферы применения экономических идей. Так, теоретической предпосылкой экономического империализма становится вытеснение политэкономии в эпоху маккартизма в США. В свою очередь, социальнополитический контекст экспансии экономики определялся обоснованием неолиберальной версии политического децизионизма в послевоенном мире. Автор полагает, что феномен «эпистемического империализма» может рассматриваться как частный случай движения к унификационизму в науке. Обращаясь к идеям правоведа Р. По-знера, автор показывает, что защитники экономического анализа права апеллируют к ценностям унификационизма. В свою очередь, критики отмечают, что его легитимация основывается на идее наращивания эпистемических ресурсов дисциплиныреципиента, поскольку научные онтологии «до» и «после» рецепции оказываются несопоставимыми. Автор считает, что империализм в социальных науках отражает тенденцию к натурализации, которая, в свою очередь, оказывается реакцией на запрос на научное сопровождение политики. Отсюда следует, что дальнейшее развитие эпистемологии социальных наук будет характеризоваться расширением эпистемического империализма. В то же время автор отмечает, что дискуссия о легитимности эпистемического империализма выходит за пределы проблемного поля эпистемологии и может быть актуальна в контексте обсуждения проблем технократизации управления в современном обществе.

Authors: Hubová Oľga , Franek Michal , Macák Marek
Published: January 2021

The article presents the aerodynamic study of solar panel assemblies and determination of wind load. In the first part, the task is solved by computer simulation of the wind flow around the proposed rectangular assembly in the scale of 1:1 using the FLUENT ANSYS program; realization of experimental measurements in the wind tunnel with a boundary layer (BLWT) in Bratislava is presented subsequently. The aim of the solution was to determine the maximum pressure and suction wind load on top and bottom surfaces of panels. The resulting net pressure coefficient represents the maximum local pressure in each panel row as maximum values from all wind directions. The experimentally obtained net pressure coefficient values were compared with computer simulation and the procedures mentioned in standard STN EN 1991-1-4. It can be seen that the inner panels are loaded considerably less than the standard defines. The panels placed on the side of the assembly or on the edge of the aisle are loaded significantly more than the standard defines. Frontal panels are also less wind stressed than in the standard defines.

Published: January 2021

Despite the very high interest from international and national financial institutions, and also enterprises from the real sector of the economy demonstrated in the distributed data storage technology, studies on the problems of assessing the use of the blockchain platform potential in the socioeconomic environment, and their theoretical understanding can be met vary rarely. As a rule, existing works reveal either the technical side of the study object or the regulatory or legal aspects of the applicability of blockchain technologies in the national economy. In this regard, this work attempts to overcome this conditional vacuum of understanding in order to make up for conditions with questions revealing other aspects of the research subject, for example, such as the economic and social effects of introducing blockchain technologies into the activities of business entities. A formalized assessment and scenario modeling of the dynamics of GDP growth in the new institutional business environment is carried out on the basis of the emerging effects assessment caused by the integration of distributed data storage technologies into the system of business operations.
Management of economical and structural changes of business in energy-intensive industrial sectors: Using the example of the petrochemical industry
Authors: Khairullin Ilshat , Khasanova Alina , Khaziakhmetova Guzel
Published: January 2021

The petrochemical industry is one of the main branches of Russian industry development. The average growth rate of the petrochemical industry in 2016-2018 was higher than in the manufacturing sector-about 5%; in 2019, it was 2.7%. The growth of production due to the high level of demand for the products of petrochemical enterprises determines the same characteristic of their investment activity. The desire of Russian petrochemical companies to develop the production of high-value products, economic analysis of production, structural analysis of production, availability of raw materials, assessment of energy intensity and competitiveness of existing technologies is extremely important. In this regard, the article is devoted to the management of structural changes in the business in the petrochemical industry. Recently, an analysis of average electricity consumption by petrochemical enterprises in Russia and abroad shows that enterprises lag far behind, although foreign enterprises produce slightly more than Russian enterprises in terms of production volumes. The main reason for the desire of enterprises to restructure are, of course, unsatisfactory values of financial indicators, there is also a shortage of working capital, large amounts of accounts payable, operating costs. In the process of enterprise restructuring, it is increasingly planned to create gas and petrochemical conglomerates-clusters that form the basis for the development of production; the production chain will be implemented from the production of hydrocarbons to the production of consumer goods.

Published: January 2021

There are many interpretations of the term reputation'. Most authors refer to the general definition of reputation, considering reputation (fr., from lat. 'Reputatio' reflection, reasoning) as "a common opinion about the merits and demerits of someone, smth". The nature and essence of the business reputation of the enterprise are multifaceted and depending on the discipline studied, each researcher has his own interpretation. As well as the very concept of reputation for various fields of science is interpreted differently, the methods of assessment differ. In this article, we analyze the Economic Assessment of the Dependence of an Organization's Competitiveness on Reputation Capital and consider the tools that form reputation capital and methods for assessing it. Based on a review of existing factors in the formation of reputation capital and valuation methods, we will be able to identify key focuses for further research. In the course of the analysis carried out in the work, we found that the formation internal factors of reputation capital play a significant role in ensuring competitiveness, namely, the organization's personnel, its corporate culture.
Liquidity and solvency of healthy and bankrupt entities: Do financial statements show any differences?
Authors: Obradović Ana , Mizdraković Vule , Obradović Maja
Published: January 2021

The aim of this paper is reflected in the analysis of the connection between the financial operations presented in companies' financial statements and the fact whether bankruptcy proceedings have been initiated against the observed companies. Namely, the fundamental indicators of a company's business success, including liquidity and solvency, are of immense significance for all stakeholders, and can also be used to predict the probability whether bankruptcy proceedings will be opened. Bankruptcy authorities make the decision to initiate bankruptcy proceedings, not solely on the basis of the results presented in the financial statements, but predominantly on the basis of the reasons defined by law. However, the question arises whether the fact that bankruptcy proceedings have been initiated correlates with the financial situation as shown in the financial statements. The paper's research sample is made up of the financial reports of two groups of companies, the first group of which includes all the companies in the Republic of Serbia that initiated bankruptcy proceedings in 2019, while the second group consists of randomly selected "healthy" companies. By applying two variables, i.e., liquidity and solvency, we are witnessing a difference in the results of the healthy versus the bankrupt companies. Healthy companies are largely liquid and solvent (47%), but it can be noticed that a number of healthy companies have problems with liquidity. Bankrupt companies are faced with a high liquidity risk, while a small number of them face the problem of insolvency.

Published: January 2021

Being a significant dimension in affective behavior education, values are guiding concepts for explaining the cognitive and social structures. In the process of value acquisition, the tendency of individuals for the value being targeted for acquisition bears a great significance. In the present study, the main aim is to develop an assessment instrument that can determine the tendency levels for the scientific values among students. In this process, the related literature was reviewed and an item pool was established. The item pool was presented to the expert opinion and following the necessary revisions, it was applied to the sample. The sample consisted of 268 secondary school students. In order to determine the validity of the scale, exploratory and confirmatory factor analysis was conducted. As a result of the validity analyses, a 4-factor structure consisting of 27 items was obtained and each factor was respectively named as the following in accordance with theoretical framework; "Curiosity", "Creativity," "Criticism", and "Inquisitiveness". The Cronbach's Alpha internal consistency coefficient, corrected item correlations, and the stability levels were calculated in order to determine the reliability of the scale. As a result of the study, it was found that the Tendency Scale for Scientific Values consisting of 4 factors and 27 items was a valid and reliable tool that can be used for determining the level of tendency for scientific values.
Science teachers' philosophical thoughts in Chemistry lessons: An epistemological reflection
Authors: Acharya Kamal
Published: January 2021

The purpose of this study is to explore the epistemological foundation of science teachers' beliefs and understanding of students' activities in chemistry lessons. It also helps to find out the philosophical perspectives of science teachers and students to accomplish practical activities to transfer school science learning to activity-based instruction. Science teachers' teaching style, students' interaction and engagement in chemistry lessons and collaborative inquiry were closely observed and their epistemologies were documented and explored. Chemistry classes with practical activities were observed in two community schools located at Province 3 (Kathmandu), Nepal. Interpretive data were generated and analyzed concerning a philosophical perspective on play-way chemistry learning. The pragmatic methodological approach was applied, focusing on the experiences of students and their collaboration with the science teachers. The analysis of activity discourse showed that the learning and understanding of chemistry depend upon the basic epistemology of science teachers, activity-based learning and the collaboration between a science teacher and the students were conducted. The results suggest that the science teachers' dogmatic epistemology is the major hindrance and an influential factor resulting in students' poor understanding in chemistry lessons.

The paper tackles the comparison of entrepreneurial intentions among students and employees in Serbia. A t-test was applied to compare individual entrepreneurial orientation dimensions, achievement dimension, and theory of planned behaviour dimensions (including entrepreneurship intention dimension). The analysis also encompassed gender as the subject's control variable. The main conclusions are 1. Risk-taking dimension, Proactiveness, and Achievement have statistically significantly higher average values for employees than for students. Students have statistically significantly higher average values of the following dimensions: Personal attitude, Subjective norm, and Entrepreneurial intention. Dimensions Innovativeness and Perceived behavioural control are equally present in both students and employees. 2. Results for female students and female employees show identical results as for the total sample. Results for male students and male employees differentiate in that the male employees' attitudes toward entrepreneurship remain high even though they have a job. 3. The highest values for Personal attitude and Entrepreneurial intention dimensions are achieved by male students, and thereafter by female students, male employees, and the lowest by female employees. 4. The minimum difference between entrepreneurial attitudes and intentions is among male students, whereas the maximum difference between entrepreneurial attitudes and intentions emerge with male employees.

Theological approach to environmental issue
Authors: Lunić Tomislav , Ćesarević Jelena
Published: January 2021

The environmental question is a multidimensional problem caused by the detrimental impact that human activity is having on the environment. Religious scholars, theologians, as well as numerous members of religious elites, in essence, view the issue as an anthropological phenomenon. In the first part of the study, we highlight several consequences of accelerated industrial development, technological growth and development: water, air and soil pollution; the shortage of natural resources due to uncontrolled exploitation; the degradation of biodiversity; climate change, etc. Additionally, in the study we focus is on man who, on the one hand, raises ecological awareness, by establishing different programs, organizations and various action plans, while on the other, through raw exploitation and the using up of natural resources, contributes to the ongoing imbalance in the ecosystem, and in essence, God's creation as a whole. The blame lies with man, and not nature. The destruction starts with the Biblical Fall and continues to this very day. In this regard, there are different solutions for switching to healthy technologies and a green economy. Institutions and organizations that deal with environmental issues are being established. Nonetheless, only the symptoms are treated, and not what is in fact the root of the problem. Thus, the theological solution is based on establishing harmony between God, man and the environment, which in the liturgical sense of the cosmos can stop the destruction of the environment, i.e., the environment as a whole. Therefore, the environment is entrusted to man as God's gift to save and cherish in a Eucharistic, liturgical, priestly manner.
Vindicae contra tyrannos: Apology of the state as a medium of social integration
Authors: Brdar Milan
Published: January 2021

In this article author presents an apology of the state in relation to modern political theory and humanity scholars and persistent criticism of such an important institution. The first section of the article provides a reconstruction of the origins of the negative attitude toward the state in liberalism, Marxism and conservativism, which have resulted in ridiculous predictions regarding the disappearance of the nation state in the context of globalization. In the second part the author asserts that the state is the unavoidable medium of modern social synthesis and deals with the problem of the one-sidedness modern ideologies and their programs of social synthesis. The principles necessary to perform this task are divided amongst ideologies (freedom - liberalism, equality - Marxism, community - conservativism), and due to this historical fact, we have conflict between them instead of complementarity. This leads to the conclusion that we ought to get rid of devotion to one ideology in favor of reform of our way of thinking. The final section of the article provides a description of the phenomena present transitional societies and the leading political role of intellectuals. In the author's view this unhappy occurrence is due to inadequate education in the area of modern political theory, which due to its negative attitude toward the state reduces our political skill. The first step to avoiding this requires the abandonment of negative attitudes toward the state and the fostering of respect of the state as the protector of the "common good" and the guarantor of liberty, necessary for the improvement of people's lives, in keeping with Aristotle's statement.

Published: January 2021

The present scientific paper discusses the issues of local and overall national development so far and in the near future within the context of a world facing increasing general threats (military, terrorist, climate, migrant, pandemic, global, etc.). The obtained research results indicate the urgent need for the setting up of adequate world organizations and their mobilization in the effort to combat and eliminate these dangers. The results also point to the appropriate directions of national and local development, which should be based on a new scientific theory of integrated local and overall social development in each country. It is within this context that Serbia was taken as an example, in whose local development there are certain problems that practically all countries in the world face. The authors propose that the way out is in the transition to scientifically based integrated local development.
Remedying the defects in India's credit and insolvency frameworks with adapted solutions from the Anglo-American legal scholarships
Authors: Iheme Williams
Published: January 2021

The law governing credit transactions in India is compartmentalized and concomitantly poses difficulties to contractual parties and access to credit: the overall effect of this is already being felt owing to the country's low rank on the 'getting credit' indicator of the World Bank's Ease of Doing Business Report 2020. The Insolvency and Bankruptcy Code 2016 (Code), being almost a mirror-image of the English Insolvency Act 1986, has some inherent defects that are incompatible with the local conditions vis-à-vis access to credit and business rescue. Some of these defects arguably emanate from the Code's unfair categorization of creditors into the 'operational' and 'financial' types, and the ensuing confusion as was witnessed in the Supreme Court's Home Buyers' case in 2019. Strangely, financial creditors enjoy some Code-given preferential treatments over operational creditors including the right to constitute committees of creditors in voting and confirming business rescue plans. The insolvency resolution process of the Code is incompatible with the fact that over 90% of the companies doing business in India are SMEs and family-owned. The crushing financial weight of insolvency resolution processes is foreseen to gradually cannibalize these SMEs and cause a sharp rise in the unemployment rate. The article diagnoses a number of defects in the credit and insolvency systems of India, and proposes transplantable solutions from the English system, the U.S. Chapter 11, and Article 9 of the Uniform Commercial Code.

Serbian Law on General Administrative Procedure (LGAP) opened a possibility for broadening the standing in administrative procedures and administrative disputes, by inclusion of subjects representing collective interests and interest of the wider public - primarily, citizen associations and similar organizations. However, by failing to regulate a series of concrete issues, the Law places the administration and the Administrative Court before a challenge, demanding from them an extensive interpretation of not only LGAP's provisions, but other legislation already recognizing such organizations as AIDS in realization of the public interest. The author analyzes relevant legislation, as well as available administrative and court caselaw in search of these answers. The lack of explicit legal provisions could be balanced by a creative approach in practice, especially by the Administrative Court. Having in mind comparative solutions, the question arises whether it is necessary to regulate this category of potential parties separately or to link it more explicitly to the already existing notion of an interested party. Instead, completely new notions have been introduced - collective interests and the wider interests of the public - which are not or not consistently defined in Serbian law. The current, not so voluminous case law, shows that the administrative bodies need a more direct indication of the rules, i.e. a more explicit definitions of these terms. However, despite the restrictive legal framework, administrative bodies should be open to understanding the specific circumstances, i.e. the motivation that an organization has when it seeks standing. In the normative sphere, one of the solutions could be to envisage the analogous application of LGAP's provisions on the interested party. Other solutions could be sought in explicitly mentioning them in the provisions on right to appeal. The current formulations of LGAP do not provide sufficient guidance to the administration and an extensive interpretation would be a great challenge for them. An active approach of the Administrative Court could show the way for the administration toward and effective application of these provisions of LGAP.

Resistance and self-propulsion characteristics of a naval ship at full scale have been investigated by using Telfer’s GEOmetrically SIMilar (GEOSIM) method based on the computational fluid dynamics (CFD) approach. For this purpose, first, the resistance forces of the Office of Naval Research Tumblehome (ONRT) hull have been computed at different three model scales by using the overset mesh technique. The full-scale resistance and nominal wake fraction of the ONRT hull have been estimated by using Telfer’s GEOSIM method. Resistance and nominal wake fraction have then been compared with those of CFD at full scale. Later, the self-propulsion characteristics of the ONRT hull have been examined using Telfer’s GEOSIM method based on the CFD approach. Self-propulsion factors at the full-scale hull have been predicted by using the SST k–x turbulence model to involve 2-degrees of freedom ship motions (heave and pitch). Rotational motion of the propeller has also been simulated by using the rigid body motion technique. The results calculated by Telfer’s GEOSIM method and the 1978 International Towing Tank Conference (ITTC) extrapolation technique have been compared with each other and discussed with those of the CFD approach at full scale. It was found that the full-scale results (both resistance and self-propulsion factors) predicted by Telfer’s GEOSIM method are closer to those of the CFD approach than those of the 1978 ITTC technique. It can be noted that Telfer’s GEOSIM method is fast, robust, and reliable and can be used as an alternative to the 1978 ITTC method for predicting the self-propulsion performance of a full-scale ship.

Introduction

Resistance and self-propulsion characteristics of a surface ship should be known properly in the design stages. For this purpose, model tests and numerical methods are used together to determine the resistance and self-propulsion performance of a ship. However, model tests are expensive and time-consuming, and the accuracy of the International Towing Tank Conference (ITTC) extrapolation technique from model scale to full scale may not have in a satisfactory level. On the other hand, Telfer’s GEOmetrically SIMilar (GEOSIM) method based on computational fluid dynamics (CFD) can overcome these difficulties.

In this study, an interactive method coupling a boundary element method (BEM) with a viscous flow solver solving the Reynolds-averaged Navier–Stokes (RANS) equations is applied to multiturbine interaction problems. The BEMis first applied to a single turbine problem to predict its performance with/without yaw in noncavitating/cavitating conditions. Improved wake alignment models, the full wake alignment and the unsteady wake alignment, are used to align the blade wake. The former is adequate for steady state with zero yaw, and the latter is used for unsteady predictions in the case of nonzero yaw in the incoming flow. The BEM results are compared with the experimental measurements and the results from full-blown RANS simulations for a range of tip speed ratios. The comparisons show satisfactory agreement between the numerical and experimental approaches. Afterward, the BEM/RANS coupling method is applied to multiturbine interaction problems with different layouts and different turbine-to-turbine offsets in an axial turbine farm. The method is shown to work well in this multiturbine interaction problem because of the capability of using a strictly Cartesian grid in the RANS method, which minimizes the artificial diffusion and improves the numerical accuracy of long-range flow development. Representation of a turbine by the body force/mass source fields in the BEM/RANS coupling approach reduces the number of cells required for 3D full-blown RANS simulations, and therefore reduces the computational cost in an efficient way.

Introduction

In recent years, interests in tidal energy harvesting have been growing because of the needs and perspectives of clean and renewable energy. Among all different types of tidal stream generators, the axial tidal turbine has been most frequently implemented because of its similarity to wind turbines and the analysis tools which are originally developed for propellers but equally applicable to turbines without extensive modifications. Because of the predominantly bidirectional flow in most tidal current sites, typical tidal turbine farms arrange the turbine in multiple lines that are perpendicular to the flow (Turnock et al. 2011). In such applications, turbine-to-turbine interaction needs to be studied to reduce the energy-shadow effect and improve the overall turbine farm efficiency.
Enhanced Unified Theory with Forward-Speed Effect Taken into Account in the Inner Free-Surface Condition
Authors: Kashiwagi Masashi
Published: January 2021

The enhanced unified theory (EUT) has been used as a core theory in the integrated system developed at the Research Initiative on Oceangoing Ships (RIOS) of Osaka University for predicting the propulsion and seakeeping performance of a ship in actual seas. In this study, the EUT is modified by adopting partially the solution method in the rational strip theory of Ogilvie and Tuck as a particular solution in the inner problem, thereby a forward-speed effect in the convection term of the free-surface condition is incorporated in the inner solution. This forward-speed effect is analytically shown to contribute only to the cross-coupling radiation forces. Some other forward-speed and 3D effects important in a low-frequency range are also included in the homogeneous component of the inner solution through matching with the outer solution in a similar manner to the unified theory of Newman. Numerical computations are implemented for a slender modified Wigley model and the RIOS bulk carrier model. Good agreement is confirmed in a comparison with experimental data for the cross-coupling added mass and damping coefficients between heave and pitch and also for the resulting ship motions, particularly in heave near the resonant frequency. The added resistance around the motion-resonant wavelength is found to be improved but sensitive to a slight change in heave and pitch motions. Thus, it is stressed that accurate prediction of the ship motions and resultant Kochin function is critical for more accurate prediction of the added resistance in waves.

Introduction

Although the design of the ship hull form has been based mainly on the propulsion performance in still water, recently, prediction and onboard data analysis for the propulsion and seakeeping performance of a ship in actual irregular waves have been attracting attention of the researchers (Orihara & Tsujimoto 2018; Minoura et al. 2019). In fact, real ships navigate mostly in rough seas, and thus, the so-called short-term and long-term predictions of ship response in actual seas must be made to guarantee the performance and safety of a ship. This trend to study the seakeeping performance of a ship is partly because the Energy Efficiency Design Index regulation was introduced by International Maritime Organization (IMO) to reduce greenhouse gas emission from the ships in operation. Thus, it becomes important to predict with sufficient accuracy the wave-induced ship motions, the added resistance, and the resultant speed loss of a ship in irregular waves represented by a directional wave spectrum (Kashiwagi 2009; Kim et al. 2017) even in the initial stage of ship design, necessitating computations for various profiles of a candidate ship.
