Assessing wave-turbulence separation from ADCP measurements with artifical flow data
Authors: Togneri Michael , Masters Ian , Williams Alison
Published: September 2023

Accurate assessment of marine currents is critical for meaningful planning of tidal stream energy deployments. Methods for assessing mean flow speed are well-established, but the issue of assessing phenomena that vary over much shorter time scales than the semidiurnal tide (principally turbulence and waves) is not as settled. This is in part due to the limitations of the standard instruments used for surveying currents at potential tidal stream sites i.e., acoustic Doppler current profilers (ADCPs). Because ADCPs use multiple acoustic beams to sample single components of velocity at widely-separated spatial locations, a reliable analysis of the mean flow can be obtained by a suitable average over measurements from all beams: this approach works well for determining mean flow properties, but is less well-suited for the smaller and faster variations associated with waves and turbulence. In particular, conventional analysis approaches such as the variance method do not meaningfully distinguish between wave-driven and turbulence-driven velocity variations.

An important consequence of this is that ADCP estimates of turbulent kinetic energy (TKE) are biased high because the TKE calculation method includes wave-driven velocity fluctuations as well as those caused by turbulence. Previous work by the authors has successfully applied a mixed spectral-statistical filter to ADCP estimates of TKE from a tidal stream test site; this filter showed good performance in distinguishing between true TKE and pseudo-TKE due to wave action. However, for field data it is only possible to assess the filter’s performance with respect to wave properties: this is because independent measurements of wave properties can be obtained from a surface buoy, but there is no alternative instrumentation that can yield independent measurements of turbulence.

The study presented here addresses this shortcoming by generating an artificial flowfield with known turbulence and wave properties, sampling with a virtual ADCP, and applying the spectral-statistical filter to the results. In this way it is shown that the combined filter improves the separation of waves and turbulence over the individual filters by an even greater degree when assessed against turbulence data rather than against independent wave measurements. The study discusses the effects of different artificial turbulence generation schemes, specifically contrasting the spectral or Sandia method with the synthetic eddy method; it also discusses the tuning of spectral filter parameters for optimum separation of wave and turbulence effects.

Published: September 2023

The M4 family of Wave Energy Converters consist of 3 rows of floats, with the front two rows rigidly connected and a hinged connection(s) to the back row.  The various possible configurations are commonly identified by the number of floats in each row – hence 1-2-1 has 1 float in front, 2 in the middle, and 1 at the rear.  A study by Stansby et al 2017 [1] showed that the 1-2-1 and 1-3-2 variants had the lowest cost of energy of all configurations studied.  The 1-3-2 variant has subsequently been extensively studied as it provides greater power per machine.  However, the 1-2-1 machine has received less attention.  In this paper we report, for the first time, wave basin testing of a 1-2-1 variant.  The design is a 1:15 scaled version of a 1-2-1 M4 suitable for deployment in the prevailing short period wind waves in King George Sound, Albany, on the south coast of Western Australia. 

 

The tests were carried out in the Model Test Basin at the Australian Maritime College, Tasmania.  This basin is 35 m x 12 m and tests were run with a water depth of 0.8 m.  For modelling operational conditions, the power take-off was represented by a pneumatic ram; in extreme seas the power take-off was removed.

 

Decay tests, irregular operational seas and irregular extreme seas were tested.  All waves were long crested.  Sea states tested were taken from the scatter diagram for the deployment site in King George Sound.  Body displacements, mooring loads, run-up on the middle floats and forces in the PTO (where installed) were measured.  Measured motions and power were compared to a linear model.  The level of agreement is compared with previous tests on other variants of M4 in the published literature, including the 1-3-2 variant tested in Carpintero-Moreno et al [2] and the 1-1-1 variant tested in Stansby et al [3].  Compared to some other configurations (such as 1-3-2) the 1-2-1 M4 is more prone to roll.  Implications of the test results for deployment in King George Sound are discussed.

Filtering device for improving the quality of cooling water in turbine generator of Sihwa Tidal Power Plant
Authors: Kim Taekyun , Kwak Hee Jin , Bang Jee Hun , Kim Mosol , Kim Beom sug
Published: September 2023

The turbine generator cooling water system of Sihwa Tidal Power Plant is an economical system in which the cooling water cools the turbine generator through a circulation pump and the rising temperature recirculates heat exchange with seawater through a surface cooler
However, as the cooling water facility continues to operate and a long period of time passes, the cooling water quality in the piping deteriorates.
In particular, increasing the concentration of Fe ions in the coolant may promote corrosion of circulating pipes, which may reduce the stability of the water turbine generator operation.
Even if the coolant whose water quality has deteriorated is replaced, additional cleaning agents must be treated, but chemical treatment was difficult due to concerns over pipe damage.
To overcome this, a filtering device for improving the water quality of cooling water was applied.
Through the application of filtering devices for about a month, the water quality was improved by reducing the concentration of cooling water Fe ions by about 70%, and the facility maintenance cost was reduced by about $110,000 per year.
We can greatly contribute to maintaining the economical cooling water system and securing the operational stability of water turbine generators by applying the cooling water filter.
Upsampling wave temporal resolution: Investigating wave parameters and the influence on WEC power performance
Authors: Mankle Hannah , Robertson Bryson , DuPont Bryony
Published: September 2023

Power production of wave energy converters (WEC) predicted in the time domain utilize wave resource parameters and time-domain hydrodynamic model simulations of the WEC. While the hydrodynamic model provides high temporal resolution of power production (10’s of Hz), the wave resource parameters are often based on frequency-domain calculations with temporal resolution of 30 minutes to an hour. However, real ocean wave conditions vary on much shorter time scales. Relying on frequency-domain calculations will not be sufficient to capture the short-term variability and accurately predict WEC power production for a standardized methodology that follows power system requirements. These requirements need forecasted data with high sampling frequency for accurate energy predictions. Looking specifically at resource characterization, high temporal resolution datasets are not publicly available or do not exist for many coastal locations. Due to data availability, low temporal resolution datasets are being used in a majority of studies to generate representative wave conditions as inputs to numerical simulations. Representative wave conditions are used to generate wave spectrums. The issue with this practice is spectrums are then used to predict the efficiency of systems that will not accurately capture the variability of waves in short timeframes. Creating a standardized methodology to increase the temporal resolution of metaocean conditions to inform model development can provide better forecasting of power production. Random amplitude, Fourier coefficient methods have been suggested for WEC simulations of finite durations to improve the observed variability in wave heights and power production. Variability using this method does increase for finite durations compared to the commonly used deterministic amplitude method. In this paper we will investigate the influence of wave parameters (significant wave height, maximum wave height, and energy period) on the prediction of WEC power production. A better understanding of the influence of these parameters will provide a path towards future standardization methodology for resource inputs for time-domain modeling.
Study with Large Eddy Simulations of energy dissipation due to backwash flows in wave overtopping.
Authors: Sandoval Claudio , Stoesser Thorsten
Published: September 2023

Renewable energy market growth is imperative to reach a sustainable society. This necessity demands improving existing methodologies to exploit green energy sources and explore new technologies. Wave energy is one of the sources with the larger offer in power available in the oceans to be harvested; however, the remoteness and extreme conditions of the best locations to harvest wave energy have made the development of wave energy converters expensive and less attractive than other green energy sources that operate on land. Overtopping wave energy converters (OWEC) operate on the shore, facilitating their construction and maintenance. They can be integrated into coastal defences, sharing the cost of construction and their environmental impact and creating new benefits from the coastal defence. The effectiveness of an OWEC relies strongly on their ability to capture wave-overtopping volumes. The geometry of the run-up ramp (slope and shape) plays an important role in the efficiency of an OWEC. An optimum geometry for each location and wave condition needs to be found to maximise the operation of any OWEC. The efficiency of these devices, quantified by the hydraulic efficiency, must be improved to make them an attractive solution for energy conversion. Three distinguishable processes occurred on the ramp of an OWEC; the wave collapse, run-up and run-down (backwash). The first two have attracted more attention from researchers, specially oriented to the design of coastal defences, but fewer studies have analysed the impact of the backwash on the energy losses during the collapse of the waves. When an incoming wave approaches the run-up ramp, it crashes against the backwash, composed of the water volume that didn't overtop the structure in the previous wave. These interactions increase turbulences and, therefore, energy dissipation, affecting the performance of an OWEC. This study analyses the hydrodynamics during the backwash flows' and incoming waves' interaction on sloped structures. A numerical code Hydro3D, based on Large Eddy Simulations, is used to conduct the present study. As a reference condition, a structure with a freeboard high enough to not allow wave overtopping is tested; in this case, all the water that run-up the slope runs down after the water tongue reaches its highest elevation. Structures with lower freeboards are tested to allow different wave overtopping levels and backwash flows. The impact of different backwash flow conditions on energy dissipation is then evaluated. The founding of this study allows us to verify if a reduction in the backwash flows can improve the efficiency of a OWEC.

Marine structures like Floating Wind Turbine (FWT) is exposed to the oncoming waves and wind that can cause oscillatory motions within the system. These undesired oscillations can have negative impacts on the efficiency of the system, reduce its lifespan, hinder energy extraction, increase stress levels, and raise maintenance costs. To mitigate these negative impacts, the integration of Wave Energy Converters (WECs) into the FWT system has been proposed. This hybrid system may be capable of extracting coupled wind-wave energy and transferring electrical power to the shared grid. This paper presents an investigation of the use of Oscillating Water Columns (OWCs), a type of WECs, within a FWT system. The purpose of using an OWC to increase the hydrodynamic damping and reduce the resonant motions of the floating wind turbines under environmental loads, including both wind and wave loads. This is because the wave energy from OWC would be very small as compared to the wind energy. However, OWCs can provide a damping source for reducing the resonant motions of the floater, especially the pitch resonant motions. This would be very beneficial for the power performance of the floating wind turbine and the structural design of the floater. The purpose of this paper is to redesign the original FWT platform to accommodate the additional OWCs by considering the hydrostatic stability and hydrodynamics since the new elements, the OWCs, can significantly change the response of the platform. The redesign of the original FWT involves the integration of OWCs within two out of three columns of an existing semisubmersible platform for a 12 MW FWT. To do this, two moonpools, which are consistent with OWC air chambers, have been created within two columns of the FWT. The water ballast was designed for the columns with and without OWCs. After that the redesign is done hydrostatic stability and hydrodynamics analyses are evaluated. The hydrodynamics properties are discussed in terms of the hybrid platform response as compared to the original platform. The hybrid platform was modeled using GeniE and the hydrostatic stability and hydrodynamics of the system was evaluated by HydroD, tools developed and marketed by DNV. The results of this study demonstrate the potential benefits of integrating OWCs within a FWT system in terms of reducing the platform oscillatory motion.

Appearance of controlling caused some chaos in managerial society. Some of them expected it as a specific kind of control which covers particular types of activities. The others expected it as new fashionable stream of management which doesn’t change anything in gist. And the thirds associate it with hard control which’s aim is to restore the total administrating at modern stage of the economic development. There are many those who still doesn’t have any knowledge about this stream and keep distance from it both in theoretic analyze and practical using. In the present article there is attempt to investigate the phenomena of controlling from the point of modern systems theory. And on this base, we try to paste it organically to the present system of managerial science. As a result, we come to opinion, that controlling is a specific addition on the top of the present managerial system. This addition has aim to conserve high level of resultativeness and effectiveness in organizational management of an investigated economic object during all the period of its life cycle.
Cambio climático, poder y vulnerabilidades en la sierra peruana
Authors: Heikkinen Anna
Published: September 2023

La intensificación de los impactos del cambio climático plantea una seria amenaza global. Las poblaciones rurales cuya subsistencia está estrechamente ligada a los recursos naturales son particularmente vulnerables ante estos cambios. Sin embargo, no hay una comprensión crítica de cómo las relaciones de poder asimétricas moldean las vulnerabilidades de dichas poblaciones bajo el cambio climático. Este artículo examina la interrelación entre las experiencias de vulnerabilidad de los pequeños agricultores vinculadas con el cambio climático y las relaciones desiguales de poder en la adaptación climática en los Andes peruanos, una región susceptible a las crecientes amenazas del clima. El análisis emplea un estudio de caso llevado a cabo en el valle del río Mantaro, en la sierra central del Perú, utilizando métodos cualitativos: entrevistas abiertas, observación participante y análisis de documentos. Los resultados del estudio muestran que, dentro del contexto del cambio climático, la producción de vulnerabilidades está asociada con las estructuras sociopolíticas, en donde no se prioriza la protección de los agricultores de la sierra. Además, la exclusión en políticas de cambio climático y otros campos relacionados, ha creado condiciones desiguales de adaptación entre los pequeños agricultores. Esto ha generado su marginación, conflictos y una mayor brecha en la vulnerabilidad climática en las comunidades andinas. Sostengo que, para tener una mejor comprensión de las diversas dimensiones de las vulnerabilidades, debemos prestar más atención a como los procesos sociopolíticos afectan las experiencias de la vulnerabilidad en ciertos contextos , y a la forma en que estos se ven configurados por las relaciones de poder desiguales en múltiples escalas.

A escala global, los expertos internacionales producen conocimientos sobre servicios ecosistémicos, muchas veces asociados a visiones tecnocientíficas del recurso hídrico. A escala local, esas visiones muchas veces compiten con reclamos de justicia hídrica y conocimiento local o tradicional, defendido por movimientos de base. Este análisis se basa en un estudio de caso en la región de Cayambe, en la sierra norte del Ecuador, donde la Confederación del Pueblo Kayambi propuso en el 2018 la creación del Fondo Plurinacional del Agua. El estudio propone un enfoque transdisciplinario combinando métodos cualitativos y cuantitativos, incluyendo entrevistas semiestructuradas, encuestas, grupos focales y mediciones de calidad del agua. Uno de los resultados principales del estudio muestra la complejidad de las interacciones y resistencias en la coproducción de los servicios hídricos entre comunidades indígenas, gobiernos parroquiales y municipales, gobierno nacional y empresas privadas, en el marco de la creación y negociación del Fondo Plurinacional del Agua.
ГІДНА ПРАЦЯ ЯК ФАКТОР ЗАЛУЧЕННЯ ДО РОБОТИ РІЗНИХ КАТЕГОРІЙ ПРАЦІВНИКІВ У КРАЇНАХ ЄС
Authors: Олександр Шубалий  , Андрій Єфімов
Published: September 2023

У цій статті вивчено суть та роль гідної праці для забезпечення більшого залучення до роботи різних категорій працівників в контексті виконання Цілей сталого розвитку ООН, зокрема Цілі 8 «Гідна праця та економічне зростання». Основна мета статті полягає у вивченні ролі гідної праці як фактора  залучення до роботи різних категорій працівників у країнах ЄС. Гідна праця була визначена МОП у 1999 році як така, що ґрунтується на принципах свободи, рівності, безпеки та людської гідності. Відповідно до МОП, гідна праця охоплює чотири основні виміри: зайнятість, соціальний захист, права працівників і соціальний діалог. Для доведення впливу гідної праці на залучення різних категорій працівників було використано результати Шостого європейського дослідження умов праці EWCS 2015. У цьому дослідженні визначено сім аспектів, пов’язаних з гідною працею, які можуть вплинути на залучення до роботи: фізичне середовище, інтенсивність роботи, якість робочого часу, соціальне середовище, навички та розважливість, перспективи та заробітна плата. Результати дослідження показали, що залежні самозайняті особи мають більш нестабільні умови праці, ніж решта професійних категорій за більшістю проаналізованих індексів. В цьому контексті важливо на рівні ЄС затвердити мінімальні стандарти для забезпечення гідної праці у різних галузях і регіонах. Зроблено висновок, що забезпечення гідної праці може стати не тільки інструментом для досягнення відповідної Цілі сталого розвитку ООН (Ціль 8), а й дієвим економічним стимулом до зростання рівня зайнятості населення, яка мала негативні тенденції протягом останніх років через пандемію COVID-19 та початок повномасштабної війни в Україні.

Iqbal's early life was driven so strongly by his antipathy for British imperialism that he failed to fully analyse the actual consequences of nationalist thought. At a period when British imperialism and Western ideologies were sweeping through the Eastern countries like a spell, Iqbal, too, criticised modern democracy and highlighted all its flaws. But Iqbal's critique was not directed against democracy per such, but rather at its flaws. In this article an attempt has been made to study the socio political philosophy of Mohammad Iqbal. It also discusses the ideas of Mohammad Iqbal on the Historic Propagation of Islam through Peaceful Measures.

Comparative Study of M30 and M35 Grades of Concrete Using BIS, ACI, and DOE Methods of Mix Design.
Authors: - Mubashir Ahmad Rather
Published: September 2023

Mix design is a critical process in concrete production that determines the optimal combination of materials to produce concrete with desired properties. In this, we will discuss three commonly used methods for mix design: the American Concrete Institute (ACI) method, the Bureau of Indian Standards (BIS), and the Design of Experiments (DOE) method.
The cement, water, fine aggregate, and coarse aggregate ratios needed to produce the desired strength and workability are calculated using the commonly used ACI technique. The ACI technique uses experimental data and historical experience to arrive at an appropriate mix design. The BIS technique, which offers recommendations for the selection of materials, proportions, and testing processes to achieve the specified strength and durability of concrete, is comparable to the ACI method.
The DOE technique is a statistical strategy that entails developing a design matrix and doing tests to ascertain the impact of various elements on the characteristics of concrete. This approach makes it possible to evaluate the variables that affect mix design in a more systematic and thorough manner, producing a concrete mix that is more effective and optimized.
In conclusion, while the DOE method is a more challenging approach that may result in more effective and optimized mix designs, the ACI and BIS approaches are frequently utilized and offer helpful guidance for mix design. In the end, the strategy used will depend on the particular needs of the project and the resources that are available.
Devastating Environmental Degradation and Genetic Engineering in Margaret Atwood’s the Year of the Flood
Authors: - S. S. Soundarya , - M. Kalaiarasan
Published: September 2023

Margaret Atwood’s The Year of the Flood (2009) is a novel about extremism and confrontation in America more clearly than any of her earlier books. The scope of Oryx and Crake (2003) has been dramatically expanded by The Year of the Flood, which takes place in the same dismal future. The Year of the Flood, a “simultaneous” that builds on Oryx and Crake’s tale and offers a more comprehensive range of critical viewpoints on capitalism and collapse, develops the story by telling it from several points of view. This paper explores a dystopian world marked by rampant genetic engineering and devastating environmental degradation, portraying the consequences of humanity’s manipulation of nature.

नकदी रहित अर्थव्यवस्था: वैश्विक परिप्रेक्ष्य
Authors: - डॉ. प्रकाश सीरवी
Published: September 2023

21वीं सदी संचार प्रौद्योगिकी के नवाचारांे से संबंधित है। विश्व के सभी देश नई-नई तकनीक का प्रयोग करके अपने देश के विकास के स्तर को बढ़ाना चाहते हैं। वर्तमान में वैश्विक स्तर पर नकदी रहित लेनदेन की ओर रूझान बढ़ता ही जा रहा है। अतः सभी देश अपने विकास के स्तर को बढ़ाने के लिए नकदी रहित लेनदेन पर बल दे रहे हैं। वर्तमान काल में संचार प्रौद्योगिकी के विस्तार के कारण मुद्रा का लेनदेन डिजिटल माध्यमों के द्वारा किया जाने लगा है। नकदी रहित लेनदेन की शुरूआत 1950 के दशक में हो गयी थी, परन्तु इसका संचालन बड़े व्यापारियों व कम्पनियों तक ही सीमित था। फेडरल रिजर्व का अनुमान है कि 2016 में कैशलेस लेनदेन यू.एस. डालर 617 बिलियन था जबकि 2010 में यू.एस. डालर 60 बिलियन था। जर्मनी में 33 प्रतिशत उपभोक्ता लेनदेन कैशलेस हैं। स्वीडन तेजी से लगभग पूरी तरह कैशलेस समाज बनता जा रहा है। 2015 में स्वीडन मंे किए गए सभी भुगतानों के मूल्य का बमुश्किल 2 प्रतिशत ही नकद लेनदेन हुआ था, जो 2020 तक 0.5 प्रतिशत तक गिर गया है। स्पेन में नकद लेनदेन की सीमा 2012 से 2500 यूरो वहीं के निवासियों के लिए व 1500 यूरो अनिवासियों के लिए है। यदि धन राशि इससे अधिक है तो भुगतान बैंक के माध्यम से किया जाता है। वहीं बुल्गारिया में नकद लेनदेन की सीमा 10000 लेव है। यूनान में 1500 यूरो तक ही नकद भुगतान की अनुमति है। विश्व के अनेक देशों में इलेक्ट्रॉनिक माध्यम से लेनदेन करने पर उपभोक्ताओं व व्यापारियों को सरकार द्वारा कर में छूट प्रदान की जा रही है।
इस प्रकार भारत नकदी रहित अर्थव्यवस्था की ओर अग्रसर होने वाला पहला राष्ट्र नहीं है बल्कि वैश्विक रूझान के कारण सभी देश कागजी मुद्रा के उपयोग को कम करने व डिजिटल माध्यमों के द्वारा नकदी लेनदेन को बढ़ावा दे रहे हैं।

Authors: - Kokila S. Mathur
Published: September 2023

Sitakant Mahapatra, Padma Vibhushan, Jnanpith and Sahitya Academy Awardee, a literary giant from Orissa, India, is deeply concerned about the dehumanization of life in our times and addresses the urgent need for revitalization of thought and the life of here and now. He advocates a return to the roots as Tradition is a song, a winged-word linking past to the present and would provide succour from scientific aridity as well as provide stability to individual psyche and social structure. Art derives spiritual energy from the mythopoeic embedded in tradition, especially of Indian culture. The creative artist must reveal his commitment to universal values which emphasize instinct, imagination and community togetherness. 'Brahman' in the marketplace, the celebration of being in the world in all its hues is Mahapatra's mantra.

Published: September 2023

Предметом рассмотрения в статье является исследование влияния перепуска воздуха мимо регенератора на характеристики когенерационных газотурбинных установок с регенерацией теплоты на частичных нагрузках при генераторном и винтовом способах нагружения. Проведенные исследования показали, что относительная теплота, переданная на теплоснабжение, возрастает, а КПД установок падает с понижением относительного расхода воздуха через регенератор при любой нагрузке. Установлено, что для микрогазотурбинных установок (МГТУ) относительная теплота, переданная на теплоснабжение, возрастает с понижением относительного расхода воздуха через регенератор и снижается при уменьшении относительной мощности. Показано, что байпасирование циклового воздуха мимо регенератора позволяет изменять потоки механической и тепловой энергии в газотурбинном двигателе независимо друг от друга. Выявлено, что на любом режиме эксплуатации МГТУ уменьшение расхода воздуха через регенератор приводит к возрастанию мощности, что необходимо учитывать в процессе регулирования.

The subject of the article is the study of the effect of air bypass past the regenerator on the characteristics of cogeneration gas turbine plants with heat recovery at partial loads with generator and screw loading modes. The conducted studies have shown that the relative heat transferred to heat supply increases, and the efficiency of the plants decreases with a decrease in the relative air flow through the regenerator at any load. It has been established that for micro gas turbine plants (MGTP) the relative heat transferred to heat supply increases with a decrease in the relative air flow through the regenerator and decreases with a decrease in the relative power. It is shown that bypassing the cycle air past the regenerator makes it possible to change the flows of mechanical and thermal energy in a gas turbine engine independently of each other. It was found that in any mode of operation of MGTP, a decrease in air flow through the regenerator leads to an increase in power, which must be taken into account in the regulation process.
