Advanced Exergoeconomic Assessment of CO2 Emissions, Geo-Fluid and Electricity in Dual Loop Geothermal Power Plant
Güler, Onur Vahip; Gürbüz, Emine Yağız; Georgiev, Aleksandar G.; Keçebaş, Ali (MDPI, 2023)Binary geothermal power plants (GPPs) are mostly encountered in geothermal fields with medium and low temperatures. The design and operation of dual binary GPPs can be difficult due to the geothermal fluid properties. This ... -
COMPARATIVE THERMAL AND FLOW ANALYSES OF TWO DIFFERENT PLATE PATTERNS FOR A COMPACT PLATE HEAT EXCHANGER
Gürel, Barış; Keçebaş, Ali; Akkaya, Volkan Ramazan; Göltaş, Merve; Kurtuluş, Karani; Güler, Onur Vahip (Knowledge Center on Organic Rankine Cycle Technology (KCORC), 2022)It is known that the most significant difference of plate heat exchangers (PHEs) from other heat exchangers (HEs) is their heat transfer efficiency. The thinness of the plates separating the two fluids compared to the other ... -
Environmental impact assessment of a real geothermal driven power plant with two-stage ORC using enhanced exergo-environmental analysis
Gürbüz Yağız, Emine; Güler, Onur Vahip; Keçebaş, Ali (PERGAMON-ELSEVIER SCIENCE LTD, 2022)Geothermal driven power plants (GPPs) with two-stage ORC are mostly used in low-temperature geothermal fields around the World. The environmental impacts of these GPPs create a gap in the literature. In this study, enhanced ... -
Experimental Investigation of a Concentrating Bifacial Photovoltaic/Thermal Heat Pump System with a Triangular Trough
Karaca Dolgun, Gülşah; Güler, Onur Vahip; Georgiev, Aleksandar G.; Keçebaş, Ali (MDPI, 2023)The heat absorbed by the heat transfer fluid for cooling a concentrated photovoltaic thermal (CPVT) solar collector can be used for purposes such as residential heating and cooking. Because of the combined production of ... -
Performance analysis of a textile based solar assisted air source heat pump with the energy and exergy methodology
Ural, Tolga; Karaca Dolgun, Gülşah; Güler, Onur Vahip; Keçebaş, Ali (Elsevier Ltd, 2021)Solar air collectors are integrated into the air source heat pump in order to increase the performance of the heat pump in cold climate regions. The evaporator air is heated by solar air collectors. In this study, two ... -
Thermo-hydraulic efficiency of lung-inspired compact plate heat exchangers made using additive manufacturing techniques with steel, aluminum and titanium powders
Güler, Onur Vahip; Gürel, Barış; Aryanfar, Yashar; Castellanos, Humberto Garcia; Göltaş, Merve; Keçebaş, Ali; Akkaya, Volkan Ramazan (Elsevier Ltd, 2024)The selection of material for compact plate heat exchangers (CPHEs) is of increasing importance due to global economic and supply constraints. Additionally, the influence of material selection on the thermo-hydraulic ... -
