Oil and gas exploration in Seferihisar Uplift (Western Turkey) containing an operable-size gold deposit: Geochemical evidence for the presence of a working petroleum system
(Springer Heidelberg, 2020)
In recent studies, the links between hydrocarbon accumulations and gold mineralizations have been examined. According to the results obtained from these studies, it has been reported that gold and hydrocarbons are carried ...
A perspective on hydrogen energy research, development and innovation activities in Turkey
(Wiley, 2020)
Hydrogen can be considered as the most promising fuel towards the greenization. Developed and developing countries around the world have formed their research, investments and directives on hydrogen. The leading countries ...
Performance improvement of the bottoming steam Rankine cycle (SRC) and organic Rankine cycle (ORC) systems for a triple combined system using gas turbine (GT) as topping cycle
(Elsevier, 2020)
In the present study, performance improvement of SRC and ORC systems used as a bottoming system in a GT based triple combined system was evaluated for varying turbine inlet temperature and pressure. In the first step, SRC ...
Performance enhancement of energy extraction capability for fuel cell implementations with improved Cuckoo search algorithm
(Pergamon-Elsevier Science, 2020)
This paper addresses an improved optimization method to enhance the energy extraction capability of fuel cell implementations. In this study, the proposed method called Dynamic Cuckoo Search Algorithm (DCSA) is tested in ...
Improving a battery charger architecture for electric vehicles with photovoltaic system
(Wiley, 2020)
In this study, a two-stage battery charger architecture with high-efficiency, multi-input, and output half-bridge LLC (HBLLC) resonance converter that performs a wide load range is proposed. The first input of the HBLLC ...
Performance analysis of a novel organic fluid filled regenerative heat exchanger used heat recovery ventilation (OHeX-HRV) system
(Elsevier, 2020)
In this study, a novel organic fluid-filled regenerative heat exchanger used heat recovery ventilation (OHeX-HRV) system was designed. Five organic-based fluids (R11, R123, R245fa, n-Pentane and Isopentane) were selected ...
Fuzzy self-adaptive PID control technique for driving HHO dry cell systems
(Elsevier, 2020)
When the standard operating temperatures are exceeded in hydroxy generators, production performance decreases and power consumption increases. Self-adaptive fuzzy proportional integral derivative systems have been used to ...
Active/reactive energy control scheme for grid-connected fuel cell system with local inductive loads
(Pergamon-Elsevier Science, 2020)
In the grid interconnection of fuel cells, local reactive loads connected to the electrical systems generate reactive power which deteriorates the power factor in the utility-grids. This situation causes energy losses, ...
Conceptual design analysis for a lightweight aircraft with a fuel cell hybrid propulsion system
(Taylor and Francis Inc., 2020)
With the ever-growing aviation industry, energy researches on aviation have turned to renewable energy sources providing electric propulsion. Fuel cells are one of the most popular sources of power for electric vehicles ...
Energy distribution analyses of an additional traction battery on hydrogen fuel cell hybrid electric vehicle
(Elsevier, 2020)
Hydrogen is the most abundant element in the world and produces only water vapor as a result of chemical reaction that occurred in fuel cells. Therefore, fuel cell electric vehicles, which use hydrogen as fuel, continue ...
