Authors: Soliman Mohab M. , Shedid Mohamed H. , El-Hameed Hala M. Abd , Abou-Ziyan Hosny
Published: July 2024

This experimental study investigates the effect of condenser configurations on the thermal performance and operational characteristics of a horizontally rotating heat pipe. The investigated parameters include three condenser lengths (112.5, 150, and 187.5 mm), outer condenser conical ends (60, 80, and 100°), and inside condenser tapered angles (1, 2, and 3°). An experimental apparatus was designed, constructed, and commissioned with nine condenser sections to explore the effect of condenser configuration on the steady-state thermal performance of heat pipes. The heat pipe is tested at a constant speed of 1500 rpm and various heat loads ranging from 25-200 W, using water as the working fluid. Results indicated that under a constant filling, charge equals the inside evaporator volume, the best condenser length of the heat pipe equals the evaporator length. Under a variable filling, charge equals 0.25, the inside pipe volume; the best condenser length equals 1.25, the evaporator length. The condenser with a conical end of 60° enhances the heat pipe performance by about 37.5-60% over the plain condenser. However, the condenser with a tapered angle of 3° produces the best heat pipe thermal performance compared to the conical end or the different-length condensers. The tapered condenser with an angle of 3° enhances the heat pipe thermal conductivity over the plain condenser by 33.3-257.8%. Also, it achieved higher thermal conductivity than the condenser with a conical end of 60° by 16.6-125.0%.

Irene Lisboa e o Jornalismo Literário na Violência Contra a Mulher. Representação Sociopolítica nas Revistas Portuguesas Seara Nova e presença (1929–1955)
Authors: Cunha Jorge da
Published: July 2024

Irene Lisboa (1892–1958) foi uma cronista, ou jornalista literária, que, a partir da voz de personagens reais ou personagens-fonte e da sua própria voz, apresenta um discurso de denúncia do cenário sociopolítico, resultado da sua posição imersiva nos locais de observação. Como revistas antirregime, e por isso censuradas, a Seara Nova e a presença, folha de arte e crítica, através dos seus autores, tentaram encontrar meios de resistir e, ao mesmo tempo, denunciar um país, um povo e, consequentemente, uma mulher idealizados. Assim, neste estudo, pretende-se compreender a representação da violência contra a mulher durante a ditadura portuguesa, numa perspetiva discursiva e narrativa, a partir do corpus cronístico de Irene Lisboa, publicado nas revistas Seara Nova e presença, folha de arte e crítica, no período entre 1929 e 1955. As conclusões apontam no sentido de que a autora deixa representada uma mulher vítima de violência exercida pelo Estado, pela família e pela sociedade. A mulher representada por Lisboa é um ser dual. Por um lado, a mulher burguesa que é formada pelo preconceito e pelo servilismo; por outro lado, a mulher do povo, também sujeita às questões de género e de poder que a desumanizam enquanto pessoa e mulher; e ambas longe da mulher idealizada pelo regime.
Examining The Impact of Inflation on Financial Development in The Fragile Five Economies with Asymmetric Cointegration Tests
Authors: Gülcü Yunus
Published: July 2024

This study examines the relationship between inflation and financial development indicators for the Fragile Five countries between 1981 and 2021. The study analysed the relationship between symmetric and asymmetric distributed lag regression models. Inflation appears to have a negative impact on financial development in countries other than Brazil and India. The results prove that the most extended correction process was experienced in India, and the shortest was experienced in Indonesia among the Fragile Five countries. Research results emphasise that high inflation negatively affects financial development in these economies by increasing the cost of financial intermediation.

Authors: Aslan Çetin Filiz , Öztürk Seyhan , Akarsu Osman Nuri
Published: July 2024

The relationship between companies' environmental, social, and governance (ESG) data and their financial performance is of significant interest. The primary aim of this study was to investigate whether the ESG scores of companies in the BIST Sustainability Index impact their financial performance. By analysing the relationship between ESG scores and financial performance indicators of 26 companies, whose ESG scores were calculated by S&P Global for the period 2018-2022, using the panel data analysis method, we found compelling results. ESG factors were found to have a significant and positive effect on return on assets (ROA), return on equity (ROE), net profit margin (NPM), and asset growth (AGR) but a negative effect on the market-to-book ratio (MBR).
The Impact of Soviet Union's Five-Year Plans on Türkiye's First Five-Year Industrial Plan within the Context of Turkish-Russian Economic Relations
Authors: Deniz Önder
Published: July 2024

The Bolshevik Revolution marked a pivotal shift in Turkish-Russian relations, ending longstanding conflicts and fostering political and economic cooperation. Notably, economic ties flourished, benefitting Türkiye significantly. Emulating the Soviet Union's Five-Year Plan, Russian experts devised an industrialisation plan for Türkiye, focusing on agriculture and underground resources. The plan's execution, aided by Soviet loans, machinery, and expert labour, saw the establishment of Soviet-style facilities in Anatolia from the 1930s onwards. The transfer of Soviet expertise and technology played a crucial role in Türkiye's industrialisation, showcasing the substantial impact of the Soviet five-year plans on Turkish industry post-1928.

Authors: Безрукова Ольга Николаевна , Самойлова Валентина Алексеевна
Published: July 2024

Современные вызовы социальной работы в сопровождении семей, особенно тех, где воспитываются дети с инвалидностью, требуют переосмысления роли отцов в воспитании и заботе о детях. В статье представлен анализ факторов, влияющих на вовлеченность отцов, выделяются ключевые принципы и направления работы, призванные усилить их участие в воспитании и обеспечить семейное благополучие. Обращается внимание на механизмы поддержки отцовства и ослабления стереотипов, связанных с мужской ролью в семье, в контексте различных социокультурных и психологических факторов, обсуждаются ограничения конструктивного взаимодействия между мужчинами и специалистами. Исходя из представленного анализа, делается вывод о необходимости изменения гендерных установок специалистов, работающих с семьями, а также широкой общественной поддержки отцовства. Статья призвана стимулировать дальнейшее обсуждение роли отцов в семейном контексте и исследование путей оптимизации социальной поддержки для семей, воспитывающих детей с особыми потребностями.
Автономность как критерий принципа адресности государственной социальной поддержки семей
Authors: Фарахутдинов Шамиль Фаритович , Мехришвили Ламара Ленгизовна , Ткачёва Нина Алексеевна , Юдашкин Андрей Валентинович
Published: July 2024

Проблема бедности семей с детьми в России остается одной из наиболее актуальных и требующих решения. Хотя монетарная поддержка представляет собой важный инструмент борьбы с бедностью, современные механизмы социальных трансфертов оказываются не вполне эффективными. Эксперты считают, что решение данной проблемы возможно за счет адресности выплат, что предполагает тщательный отбор получателей государственной поддержки на основе четких критериев. Однако реализация этого подхода сталкивается с серьезными препятствиями, среди которых ‒ ограниченность существующих теоретико-­методологических наработок и необходимость расширения научного арсенала для более эффективного определения семей, нуждающихся в поддержке. В статье рассмотрен концепт автономности как основы для определения адресности социальной поддержки семей. Показано, что традиционно используемое в социальной политике понятие «благополучие» не позволяет полностью решать проблемы семей, в то время как автономность может служить более точным и эффективным критерием. В ходе эмпирического исследования, реализованного через анкетный опрос семей в Тюменской области и с помощью кластерного анализа, авторы построили типологию семей на основе уровня их автономности. Результаты показали вариативность автономности семей и ее зависимость от множества факторов, в том числе территориальных. Авторы обращают внимание на ключевую роль в обеспечении качества жизни семей региональной политики, на важность адаптации социальной поддержки к специфике каждого региона и необходимость учета индивидуальных особенностей и потребностей семей при формировании и реализации мер поддержки.

Methodological Reflections on Studying Gender‐Sensitive Parliaments Cross‐Nationally: A “Most Significant Change” Approach
Authors: Ahrens Petra , Erzeel Silvia , Fieremans Merel
Published: July 2024

Whilst cross-national comparative analyses provide distinct opportunities for the study of gender-sensitive parliaments, the inherent challenge in conducting comparisons necessitates a continued search for innovative methods. This article responds to this need by proposing the “most significant change” (MSC) approach (Davies & Dart, 2005), which centres on collecting and analysing “stories of significant change.” Drawing on our own application of MSC in an international study commissioned by INTER PARES, we show that MSC’s bottom-up, inductive, and participatory approach proved valuable in uncovering hitherto unknown instances of gender-sensitive changes across countries, illuminating the broader impact of such changes beyond parliaments and incorporating practitioners’ perspectives. The flexibility of MSC also enabled context-specific applications, which we illustrate through three examples from Cyprus, Germany, and Trinidad & Tobago. By offering a complementary approach to compare parliaments’ gender sensitivity across countries, our study provides a novel perspective for future comparative analyses in the field.
The Functional Peculiarities of Image Usage in BBC and CNN News Texts
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, HETMAN Viktoria
Published: July 2024

The article highlights the usage of images in BBC and CNN online news. The main communicative functions performed by images are considered to be as follows: image as illustration used to depicture the reality; image as evidence used to prove the facts; image as sensation used to evoke great surprise, excitement, or interest among a lot of people; image as evaluation used to carry huge emotional appeal; image as icon which functions as symbolic representation of key moments in history, war issues, critical moments embedded in the national psyche; images used to invoke aesthetic appeal. The text-image relations were also analyzed in the current paper. Based on Martinec & Salway detailed classification of the text-image relations the following relationships types were spotted in the BBC and CNN news discourse – those of equal and unequal image & text status. Equal status presupposes the independent and complementary text & image relations where the latter are joined on an equal footing without one modifying the other. Unequal status indicates text & image subordination that could be revealed via the presence of textual implicit devices to be decoded by reference to an image. Thus, the relatedness between images and texts is realized by means of componential cohesion, which relates participants, processes and circumstances in images and texts. From the logico-semantic perspective the news text & image relations of extension, enhancement and exemplification may be identified. The extension relationships are manifested by adding new, related information either to a text or to an image. In enhancement relationships a text or an image qualify each other circumstantially by naming time, place or reason. The exemplification relations are realized by providing some special details to more general information presented either in a text or in an image.
Language Dimension of Information Manipulation on Ukrainian Telegram Channels
Authors: Holota Taras ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: July 2024

The research delves into the challenges posed by the full-scale russian invasion, emphasizing the need for an effective counter-propaganda strategy online. The digital proximity of Ukraine and russia means users often consume information from diverse sources, sometimes antagonistic. With the growing influence of social networks and messenger platforms like Telegram, the study underscores the urgency of understanding and countering information-psychological operations. Our research also differentiates between intentional and unintentional manipulation, highlighting the varying objectives behind each. An analysis of 4,100 posts (encompassing approximately 246,000 word usages) from popular Ukrainian Telegram channels such as “Труха 􁍮􁍯Украина”, “ЧОРНИЙ ЛИСТ,” and “Український Телеграм” was conducted to determine the proportion of content associated with manipulative attributes. An attempt was made to underscore the importance of evaluating the quality of content in Ukrainian Telegram channels as well as identifying the percentage of content that contains information and emotional manipulation. Within the selected study period, 29 % of manipulative content was found on the “Труха 􁍮􁍯Украина” channel, 12% on the “ЧОРНИЙ ЛИСТ” channel, and 3.3 % on “Український Телеграм.” It was determined that the most frequent linguistic and extralinguistic tools for information manipulation include the use of emojis and emotionally charged vocabulary, appeals to authority, specific word capitalization, lack of primary source citation, structuring messages with a focus on unverified information, calls to action, and the use of circumstantial adverbs of time to create a sense of urgency, among others. Moreover, typographical errors, incoherent presentation of information, and grammatical mistakes were identified as other key markers of manipulative messaging. These seemingly inadvertent errors could potentially be deliberate, further muddying the waters of information clarity.

Power to the programmer: Modeller’s perspective on automating the setup of hydrodynamic models for Dutch water authorities
Authors: Remmers Janneke , Teuling Adriaan , Dahm Ruben , Van Dam Arthur , Melsen Lieke
Published: July 2024

Use of models in decision making, for example in water management, requires confidence in the model and its outputs. Since choices in model setup affect model output, this confidence is affected by the modellers’ professional judgement. Computer programmers can use their expertise in coding to standardise some of the tasks associated with computational modelling. Therefore, centralized automation has the potential to ensure quality of modelling decisions. Since it is the modeller that makes the choices in the model set-up, it is important to understand how modellers perceive automation. To explore their perspectives, we conducted fourteen interviews with modellers at water authorities and consulting companies in the Netherlands. The transcripts were analysed through deductive and inductive content analysis. Our study reveals that automated modelling processes can improve efficiency, transparency and consistency, but only if certain requirements are met, such as good documentation, clear ownership, adequate maintenance, and frequent evaluation. Therefore, managing the risks and benefits of automation requires balancing the power between modellers and programmers.

The majority of conventional chemotherapeutic agents cause cell death by directly inhibiting the synthesis of DNA or interfering with its function. This means that they are often not tumour-specific and are associated with considerable morbidity. Patients undergoing cancer therapy may experience unwanted side-effects involving the oral cavity and more evidence is emerging regarding the management of these complications. These oral effects have both short and long-term implications. Most of the side effects gradually disappear after the end of treatment, though in some cases permanent damage may be observed at cardiac (myocardiopathy), pulmonary (fibrosis), renal (chronic renal failure) or reproductive level (sterility).
Federalism and the Formation of UAE Elites after 1971
Authors: Adrianov Artem
Published: July 2024

The paper studies the formation of the political elites of the UAE after the country had gained independence in 1971. The author pays special attention to the way federal system influenced this process. On the one hand, it reduced the severity of rivalry between the emirates, and on the other hand, consolidated the political order that existed in 1971 and the process of formation of elites. As centralization processes gained pace in the 1970–1980s, federal authorities gained more influence. However, full-fledged federal elites in the UAE, due to the peculiarities of the government structure, never appeared. It seems that every member of the federal elite is somehow connected to the emirate from which he comes. At the same time, within the federal authorities, especially the Cabinet of Ministers, the influence of Dubai, as well as the northern emirates, began to decline. Abu Dhabi’s role as the richest and most influential emirate continued to grow, giving it the largest representation in the Cabinet. In this regard, the article analyzes the biographies of some minsters from Abu Dhabi that make part of the UAE cabinet, as they are considered to be the most representative members of the so-called federal elites. The influence of tribal origin and close relations with the leadership of the emirate in career growth of particular ministers is assessed.
The Triumph of Korean Christianity in Russian Federation
Authors: Filatov Sergei B.
Published: July 2024

At the end of the 19th century, Protestant churches arose in Korea (the most numerous and influential are Presbyterians and Methodists) and their numbers and influence grew explosively. Protestantism has played an important role in the modernization of South Korea. The mythologeme has been established in the minds of Koreans that they are a chosen people who are destined to convert all mankind to Christ. In 19th century Korean Protestants sent missionaries to many countries, including Russia. In 1909, missionary activity began among the Koreans of Primorye. Despite the resistance of Archbishop Eusebius of Vladivostok and Kamchatka, the missionaries converted a significant number of Koreans living in Primorye to Protestantism. In the 20s and 30s, the Soviet authorities destroyed the Protestant churches of the Far East, and the Koreans were deported to Central Asia in 1937. During the years of Perestroika, tens of thousands of Koreans returned to Primorye, and South Korean missionaries revived Protestant churches among them. Korean churches began to play a prominent role in religious, cultural life and social ministry. Their role in inter-church cooperation is significant. They themselves began to send missionaries to Central Asia. In the post-Perestroika period, Russian Koreans had mutual misunderstandings and conflicts with missionaries from South Korea, because Russian Koreans were strongly assimilated into Russian culture. This ensured their success in missionary work among Russians. The missionaries left Primorye and the churches became completely independent. Now more than 50 % of the parishioners of Korean churches are Russians, and the churches themselves are losing ethnic Korean features.
TOOTH HARMONICS IN THE VIBRATION DIAGNOSTICS OF GEAR TOOTH WEAR IN A GAS TURBINE ENGINE
Authors: Sundukov A. E. , Shakhmatov E. V.
Published: July 2024

Vibration diagnostics in the most effective non-destructive method for testing technical condition of rotor machines. A widely used diagnostic indicator of gear defects is the intensity of the n-dimensional vector from a series of tooth harmonics. For planetary gearboxes of aircraft engines, the higher harmonics intensity is often commensurate with the vibration noise intensity, which reduces the effectiveness of its application. On the example of the tooth flank wear in NK-12 engine differential gearbox, we have demonstrated the possibility of diagnosing this defect based on the intensity of tooth subharmonics.

Published: July 2024

The article considers the implementation of designs of known samples of various types of flow parts of control pipeline valves in terms of their noise level in various operating modes. The hydraulic and acoustic characteristics of such flow parts have been studied. The range of tasks that need to be solved in the development of advanced flow parts with increased requirements for low noise has been determined. Technical solutions have been formulated to achieve a reduction in noise and vibration levels per unit of dissipated hydraulic power using accumulated experience and the latest technical solutions. The advantages and disadvantages of various designs are determined in terms of operational and functional characteristics. The main principles for the choice of design solutions are formulated, taking into account the noise and vibration characteristics to be laid, confirmed by the calculated data and the results of experimental studies of the flow parts. Directions for additional research are outlined.

A Case of Mirizzi Syndrome with Pancreatic Divisum
Authors: Muthuvel Divya , Soundarapandian Anita
Published: July 2024

Mirizzi syndrome (MS), a rare complication of gallstones, refers to extrahepatic biliary compression by calculus in the cystic duct or Hartman’s pouch and is usually associated with cystic duct abnormalities. Its association with pancreatic divisum(PD) is infrequent, the most common complication of PD being recurrent pancreatitis. We report a case of 39-year-old female who presented with acute abdominal pain to the department of general surgery, Chennai, Tamil Nadu, India in August 2022. Magnetic resonance cholangiopancreaticography (MRCP) showed calculous cholecystitis with a calculus indenting the cystic duct, causing luminal narrowing of the common hepatic duct (type I), which was associated with type II PD. The association of MS with PD has been rarely described. PD may be one of the factors responsible for bile stasis leading to calculous cholecystitis and its complications. Knowledge of MS and its associations helps in early diagnosis and selection of appropriate treatment management.

Este estudo investiga o impacto da Netflix na indústria audiovisual brasileira, com ênfase na suposta diversificação introduzida pela plataforma no Brasil. Objetivamos analisar a dualidade inerente a esse fenômeno, reconhecendo o papel desempenhado pela empresa na ampliação das narrativas brasileiras. Argumentamos que, embora a Netflix proporcione uma plataforma global para essas obras, há o potencial de perdermos a soberania sobre a representação do Brasil e da brasilidade no cenário internacional. Por meio de uma metodologia que incorpora uma análise crítica das estratégias de localização da Netflix no mercado brasileiro, investigamos como estas acabam por diversificar representações nacionais, em um cenário historicamente monopolizado pelo Grupo Globo. Contudo, apontamos, que a Netflix reduz alguns imaginários a estereótipos ou a obras esvaziadas de autenticidade cultural. Este estudo, assim, contribui para uma compreensão das complexas interações entre a produção audiovisual local e os serviços de streaming de vídeo estrangeiros em um mercado do Mundo Majoritário ainda não regulamentado.

Ethyl p-methoxycinnamate (EPMC) have a lot of bioactivities, such as analgesic and anti inflamation by inhibiting COX. It is promising to be modified as a COX-2 selective inhibitor, due to its characteristic structure. In this study, EPMC as the starting material was isolated from Kaempferia galanga L. and being reacted with hydrazine hydrate to obtain p-methoxycinnamoylhydrazide. This synthesis was carried out using conventional thermal heating and microwave irradiation. Microwave irradiation was one of the methods that could reducing reaction time and increasing yield. The product was purified by column chromatography to give a purified product, which was analyzed using TLC test, melting point test, IR, 1H-NMR, and UV spectroscopies to determine its structure. It can be concluded that the product was not p-methoxycinnamoylhydrazide, but 3-(4-methoxyphenyl) propanehydrazide with 0,76% yield by conventional thermal heating and 7,90% yield by microwave irradiation.

Background: Regenerative endodontic treatments are classified based on approach in the procedures and principles. One is cell-free approach that involves a revitalization procedure to achieve continued root growth while the other is cell-based approach which involves pulp/dentin regeneration through isolation and ex vivo expansion of stem cells seeded in the scaffold and then transplanted into the canal space. Technically, the cell-free approach is simpler than cell-based approach because the former does not concern about external stem cell isolation and culture. Currently, the gold standard and the one that has been clinically performed is cell-free approach. Cell-based approach is still not a standard because currently the cell-based approach is still in the clinical trial stage. Purpose: to evaluate the biological basis and clinical protocols recently used in regenerative endodontic treatment and discuss potentially future treatment approaches. Review: The literature review was searched in PUBMED with the keywords: immature permanent teeth, pulp revascularization, stem cells and regenerative endodontics. The regenerative endodontic treatments with various procedures and techniques result in a significant increase in root length and dentinal wall thickness. Stimulation of stem cells in apical root canal system is required to induce tissue formation and continued root maturation. Conclusion: The success of regenerative endodontic therapy relies on the development of a technique that enables clinicians to create functional pulp tissue within cleaned and shaped root canal systems. It is hoped that further research studies are required to define advantages and limitations of cell-free and cell-based approach.

Background: Pulp capping is one of the treatments for reversible pulpitis and aims to maintain pulp vitality. This treatment requires a material that can protect the pulp with good biocompatibility. The physical and mechanical properties, bio interactivity and bioactivity of pulp capping materials are very important for the formation of reparative dentin. Calcium hydroxide (Ca(OH)2) as the gold standard material in pulp capping treatment also has some disadvantages. Another alternative for pulp capping material is blood clam shell because it contains 98% calcium carbonate (CaCO3), which is a compound with a bone-like structure and can induce pulp cell differentiation. Objective: To investigate and explain the difference in compressive strength between CaCO3 from blood clam shells and Ca(OH)2  as a candidate pulp capping material. Methods: This research is a laboratory experimental study with post test only control group design method. Ca(OH)2 and CaCO3 samples were formed with a mixture of powder and aquadest with 4x6 mm sample size. The samples were dried at room temperature and the compressive strength was measured using a universal testing machine (UTM). Result: There is a significant difference in compressive strength between Ca(OH)2 and CaCO3 blood clam shells in the Mann-Whitney test results (p<0.05). Conclusion: The results of the compressive strength test between the mixture of Ca(OH)2 with aquadest in a ratio of 1:1 are greater than the mixture of CaCO3 blood clam shells with aquadest in a ratio of 3:1 so that pure CaCO3 blood clam shells with distilled water without other additives cannot be used as a candidate for capping pulp material.

Published: July 2024

Background: Nanohybrid composite resins have many advantages, but one disadvantage is their absorbent nature which can lead to discoloration.  Phenols and flavonoids in nano propolis cause diffusion and affect the matrix and pigments of nanohybrid composite resins. The accumulation of reduction-oxidation reactions causes new compounds of nanohybrid composite resins to occur so that they have different colors. Objective: The study was conducted to determine the changes in surface color of nanohybrid composite resin after immersion in nano propolis at 5% concentration. Methods:  Research experimental laboratory method with pre and post test design was applied to 25 nanohybrid composite resin fruit samples of size (5x5x1.5) mm embedded in bovine incisive, then immersed in 5% nano propolis and 25 ml of distilled water at 37oC for five days.  The color change (ΔE) was measured with a DSLR camera and processed with Adobe Lightroom Classic software in CIE L*a*b* format. Results: The anova test on ΔE in the data showed the p-value of sphericity assumed was smaller than 0.05. There is a difference in the average measurement results on the first day to the fifth day in the treatment group. Independent t-test of control and treatment data showed a significant difference in measurement results. The results of the post hoc test with the Tukey method showed that the treatment groups at 4x24 hours and 5x24 hours did not have significant differences. P-value at 4x24 hours and 5x24 hours was 0.957. Conclusion: There was a change in the surface color of the nanohybrid composite resin after being immersed in a nano-solution of propolis with a concentration of 5%.

Nest predation is a chief cause of reproductive failure in birds, warranting defensive strategies such as nest concealment. This note reports an observation of a Superb Fairy-wren Malurus cyaneus nest built on top of a sedge grass enclosed by a tree guard at a tree-planting site in Bega, New South Wales. Although this meant that the nest was lower to the ground than a typical natural nest, its situation within the tree guard might have conversely offered the benefits of visual concealment and a physical barrier from nest predators. With at least three nestlings close to fledging age present, this nesting attempt would be considered successful. This outcome is significant in light of high rates of nest predation observed in other studies.
Exploration of Two Different Length Scale Refinement Strategies on the Application of SPH Simulations on 3D Free-surface Flows
Authors: Tran Nam , Roberts Jon , Hastie David
Published: July 2024

A length scale refinement study is a standard practice to ensure the independence of a numerical model on spatial approximations. For smoothed particle hydrodynamics (SPH), the process of length scale refinement study tends to be conducted based on experience. A challenge of defining a universal length scale refinement strategy is the existence of two length scales – particle spacing and smoothing length. Despite the challenge, further investigations of the impact of different refinement strategies should be continually conducted to improve the reliability of practical SPH applications on 3D free-surface flows. In this study, a conventional strategy and a novel coupled refinement strategy are used to investigate the convergence of SPH simulations for free-surface flows using a standard SPH scheme available in an open-source framework. The two case studies are a dam break flow and a lesser-known stable regime water flow inside a rotating drum with lifters. Validations are conducted using existing literature data for the dam break flow and laser Doppler velocimetry (LDV) measurements for the rotating drum flow. The investigation shows that the proposed coupled length scale refinement strategy does not offer a significant improvement for the SPH model of the dam break flow comparing to the conventional strategy. On the other hand, the stable regime rotating drum fluid flow shows that both refinement strategies are not sufficient to tackle SPH’s on-going fundamental challenge of accurately predicting the flow field of complex 3D turbulent flows with free surfaces.
