There are many contributing factors to the negative impacts on the environment, one of them being the automobile sector. Today, most cars are driven on fossil fuel, which produces toxic emissions. The search for replaceable alternative fuels were considered mainly and the keys to demand are renewable energy and energy-friendly resources. Hydrogen as a fuel, in particular hydrogen gas, is one of the options considering the only residues to be water and hot air, provided that the energy used in the hydrogen production comes from renewable sources. In the storage tanks of cars fueled by hydrogen gas, a high pressure is set due to its advantages of more storage opportunities and thus increased mileage of the tank. A decompression process is necessary to supply the fuel cell with hydrogen gas at the right pressure and thus achieve the highest possible degree of efficiency. The concept offers a wide set of application opportunities in industrial situations, and understanding the valve is important for characterizing the performance of the device. In other words, high performance could be achieved with correct and optimal geometry on the Tesla valve. In this work, the geometric parameters were investigated in order to determine their ideal value for optimizing the performance. The parameters of interest were the optimum operating conditions of the valve. A numerical observation was conducted using simulations in a Computational Fluid Dynamics program, ANSYS Fluent, in order to obtain the results.","PeriodicalId":337301,"journal":{"name":"i-manager’s Journal on Future Engineering and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117237690","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}

This research employed 11 General Circulation Model (GCMs) from both generation of models and combined them from both Multi Model Averaging (MMA) and Bayesian Multi Model Averaging (BMA) to ascertain the upgradation in projections for both seasons. BMA method offer better alternative to MMA as higher weights are assigned to better performing models for more skillful regional projections. Our results elucidate the fact that both combinations of models and methods inform spatially similar non-uniform changes in projections of precipitation across these models. The models do not express much progress in mean simulations for both 20th and 21st century projections. Thus lower uncertainty for CMIP5 group than CMIP3 is observed. Therefore, the findings highlight that mere comparisons based on mean statistics alone may not be sufficient to understand their progress. However, advanced methods of analysis provide better insights in their model development.","PeriodicalId":337301,"journal":{"name":"i-manager’s Journal on Future Engineering and Technology","volume":"271 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133781829","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}

It is a concern that conventional natural gas resources will be unable to meet growing supply requirements. This concern has prompted a scramble to secure long-term natural gas supplies. In a high oil and gas price environment, unconventional resources are viewed as important and economically attractive components of future natural gas supplies. Shale gas is natural gas produced from shale formations. Gas shales are organic-rich shale formations. Shale gas is a dry gas composed of methane. Various factors which have contributed to its rapid development are mainly advancements in horizontal drilling, hydraulic fracturing, and, perhaps most importantly, the rapid increase in natural gas prices in the last several years as a result of significant variation in supply and demand. India has a high potential for shale reserves. According to the available data, a comprehensive shale gas pilot project carried out in the Damodar Valley Basin has made an initial gasin- place estimate of 300 to 2,100 trillion cubic feet (TCF) in Indian shale gas basins, which is around 300 times higher than the Krishna Godavari Dhirubhai 6 (KG-D6) basin, by far the largest gas field in the country. In this paper, a brief review of shale gas reserves across the world and their government policies has been explained.","PeriodicalId":337301,"journal":{"name":"i-manager’s Journal on Future Engineering and Technology","volume":"967 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132592073","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}
