An experimental study has been carried out to determine the torque developed by different configurations of hybrid hydrokinetic rotors and presented in this paper. The study was carried out for different Reynolds numbers of 1.35x105, 2.24x105 and 3.14x105 corresponding to different water velocities. Based on the experimental study, it is found that the hybrid hydrokinetic turbine rotor having a Savonius helical blade angle of 0°, performed better in comparison to other configurations. The maximum average torque is observed as 0.36 for a hybrid water turbine rotor having Savonius helical angle of 0° corresponding to TSR value of 0.61 and Reynolds number of 1.35x105. The results of this study may be useful to develop a prototype for field study.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121964736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work aims to illustrate the energy saving that can be realized by using a bleed-less aircraft environment control system (ECS) that is powered by an auxiliary ram air compressor: This paper presents a direct comparison between the energy consumption of a conventional bleed air system and a bleed-less ECS. A conventional bleed air ECS system is first modeled using MATLAB and validated with results in the open literature. The system is modeled to match the temperature profile with that of an Airbus 320 during cruise conditions. Then, a bleed less system is modeled by modifying the bleed air system to use a ram-air compressor for the air intake as a bleed less ECS. Finally, the fuel mass penalties associated with each environment control system are calculated. The bleed air system incurs fuel penalties due to bleed air extraction, and additional drag due to the ram air intakes for the large heat exchanger ram-air scoops. Whereas the bleed-less system incurs penalties due to drag from the small ram-air intakes for the heat exchanger and the ram air compressor scoop and a dedicated electrical power system for the ram air compressor. It was found that the total fuel mass penalties calculated for the bleed less system are about 80% lesser compared to a conventional bleed air ECS without a dedicated electrical power system.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122568541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most cost-effective operation and sizing of an MG necessitate the use of optimization techniques. MGs are optimized using a variety of methodologies, including gradient based and non-gradient-based algorithms. Particle swarm optimization (PSO) is a non-gradient-based evolutionary algorithm used for cost optimization due to its high performance and ease of implementation. Regarding microgrid operations and sizing, the effectiveness of several economic models based on PSO is discussed in this paper. A 10-kW generator system is a part of this system. It is divided into two generation units: one that produces PV power and the other that produces wind power. There are 5 kW in each generation system. These are coupled to the DC micro grid. The cost function and the constraints of the microgrid are described and its performance is analyzed using particle swarm optimization (PSO) algorithm. The convergence graph for the cost optimization of microgrid using PSO algorithm is presented in this paper. The simulation results of the system shows that the loss of load probability (LSPS) is around 1 % and the cost of energy (COE) is 6.03 $.

A huge number of travelers visit from home and abroad. However, severe electricity shortages are hindering its transformation towards a smart city. The existing ground mounted solar PV and diesel generator is insufficient to meet the rising load demand, causing visitor dissatisfaction. The ocean wave converter can extract a significant portion of energy from the surrounding Bay of Bengal that has not yet been analyzed. This study proposes a grid independent microgrid energy management planning addressing Sustainable Development Goal 7 (SDG7). The energy demand is estimated under smart city context. The HOMER software optimizes four distinct microgrid topologies, comprising of ground PV (GPV), floating PV (FPV), wind turbine generator (WTG), bio-diesel generator (BDG), eco wave power (EWP), bidirectional converter (BDC), first life battery (FLB) and second life battery (SLB). The results shows that the GPV/FPV/WTG/EWP/BDG/BDC/SLB hybrid architecture is most favorable configuration achieving SDG 7. This topology is affordable, reliable and sustainable for the remote area. The sensitivity analysis is also performed. Overall, the work provides policymakers the multidisciplinary expertise needed to transform a small island towards a tourist-intensive smart city using local energy resources while also ensuring decent lifestyle for islanders.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114236759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanorefrigerants represent outstanding thermal, rheological, and heat transfer properties. This conference paper describes the theoretical analysis of Single Walled Carbon Nanotubes (SWCNTs) nanoparticles for volume concentrations of 0.5, 1, 2, and 3 vol. % in R134a and R152a refrigerants to determine thermal conductivity, viscosity, Coefficient of Performance (COP), and energy savings. This paper concludes that the Coefficient of Performance is enhanced for both nanorefrigerants due to the remarkable thermal conductivity of nanoparticles. The R152a-based nanorefrigerants have shown a maximum coefficient of performance values than R134a-based nanorefrigerants. The maximum increment in Coefficient of Performance was reported about 1.43%for R152a-based nanorefrigerant as compared to the base refrigerant R152a. The results show an increment in thermal conductivity with increasing volume concentration with the maximum enhancement of 1.94% for 3 vol. %. The viscosity of nanorefrigerants increased with increasing volume concentration. The R152a-based nanorefrigerant reported minimal viscosity values than R134a-nanorefrigerant. The maximum annual energy savings with nanorefrigerants is reported for about 4819.08 kWh/year, which aids in achieving lower global warming emissions. To summarize, R152a-based nanorefrigerants in refrigeration applications are more promising to increase the performance and reduce the energy consumption than R134a due to their higher COP value and environmentally friendly nature.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115675003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
