“Solar assistaed hydrogen production via PV/T assisted small scale transcritical power cycle withdirect steam generation”
【講義概要】
The objective of the proposed study is to examine the performance of an integrated hydrogen generation system based on solar energy. For this purpose, CO2, a natural fluid that does not harm the environment, was used as the working fluid. The system is comprised of the Photovoltaic/thermal (PV/T) panels, a pump, a condenser, a turbine, a Proton Exchange Membrane Electrolysis Cell (PEM-EC), and hydrogen and oxygen storage tanks. MATLAB and EES software programs are utilized to perform the performance assessment of the system. According to the analysis made on data for a specific date, the net power generation from the PVT panels was calculated as 2696 W, the net power generation from the transcritical C02 Rankine cycle was 73.03 W, and the hydrogen production was 0.514 g/h.
Fig.1 shows the schematic representation of solar-assisted hydrogen production system by PV/T assisted transcritical power cycle with direct steam generation. The PV/T system converts solar energy into electricity and heat energy. The output thermal energy of the PV/T system drives the transcritical sCO2 cycle to generate more electricity. Thus, the total electricity generation from solar input is increased by combining the PV/T system with the transcritical sCO2 cycle. Lastly, the generated electrical energy is transmitted to a PEM-EC to produce hydrogen, which is the main objective of this work.

“Numerical simulation of coupled thermal radiation and natural convection in a cavity”
【講義概要】
This talk will cover a fundamental theoretical study made to understand the interaction of surface radiation and natural convection in an air filled cavity with a centrally placed thin heated plate. The Finite Volume Method is used to obtain the results for a wide range of parameters such as the Rayleigh number, plate length and emissivity. The results indicate a better homogenization of the temperature field by radiation. It is also found that the contribution of the convective mechanism to the overall heat transport increases with emissivity when the plate is horizontal whereas decreases when it is vertically placed.
