This work depicts the steady-state single phase transport of reactants and water in a three dimensional computational domain of a low temperature Polymer Electrolyte Membrane Fuel Cell. The model computational domain includes anode and cathode flow channels, gas diffusion layers, membrane and catalyst layers. Both anode and cathode mass and momentum transport phenomena in the flow channels, gas diffusion layers (GDLs) and porous electrodes are included in this study. A Computational Fluid Dynamics code using the finite element method (FEM) is applied on the studied domain. Water analysis in the membrane will be discussed in further works. Mass transfer analysis focused on the air flow velocity parameter, a range of values is applied to observe its effect Simulation results show an important molar concentration of water in the cathode side compared to a low one in the anode side. A good oxygen concentration is obtained with an air flow velocity of 0.5 m/s, increasing this value may cause the membrane flooding phenomena.","PeriodicalId":129568,"journal":{"name":"3rd International Symposium on Environmental Friendly Energies and Applications (EFEA)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123386621","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 numerical model simulates the effect of the operating and meteorological parameters of Northern Egypt area on the total performance of each component of the plant. A study of the operating parameters of the PTC performance was also presented in this paper. The plant uses the Therminol-VP1 as a storage media and also as a heat transfer fluid with flow rate ranges from 0.9 to 1.8 kg/s for the solar collectors. It's used also as a heat source for the ORC and the absorption chiller with a flow rate range from 0.3 to 0.9 kg/s. This paper presents four operating modes for the plant which are electric generation, cooling, heating and electric generation with heating modes. The model studies also the effect of these operating modes on the plant performance. The simulation model proves that the PTC produces a maximum thermal power of about 70 and 115 KW in winter and summer respectively. It proved also that the designed plant collect thermal energy ranges from 640 KWh to 1186 KWh during the first six months from Jan to Jun, respectively. The plant can produce also daily electric energy range from 69-85.5 KWh during the same period.","PeriodicalId":129568,"journal":{"name":"3rd International Symposium on Environmental Friendly Energies and Applications (EFEA)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127010081","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 realisation of the substantial unexploited hydrokinetic energy of tides is currently driving hydrokinetic turbine research. In contrast to wind turbines, tidal technology has not yet reached maturity and new designs are required in order to take into account cavitation, leading edge roughness, and the high energy density of flowing water. In particular, reinforced blade structures are required to deal with the high hydrodynamic loads experienced by tidal turbines. In this research, the potential benefit of using bend-twist adaptive blades on tidal turbines in order to reduce hydrodynamic loads is explored. A Tidal Turbine Hydrodynamic code (TTHydro) capable of simulating tidal turbines equipped with adaptive blades is developed and validated. It is found that employing bend-twist adaptive blades on variable-speed pitch-controlled tidal turbines reduces both power and loads. It was also observed that a substantial reduction of hydrodynamic loads could be achieved at the price of a small power loss.","PeriodicalId":129568,"journal":{"name":"3rd International Symposium on Environmental Friendly Energies and Applications (EFEA)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132509526","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}
