Thermal performance of thermochemical reactor based on 5kW solar simulator
A solar thermochemical reactor was designed based on a 5 kW non-coaxial concentrator simulator,and a mathematical model of the thermal performance of the reactor under concentrated irradiation was established.The model was used to calculate the influence of solar simulator power,material emissivity of reactor inner wall,working pressure and inlet velocity on the temperature distribution in the reactor.The results show that increasing the power of the solar simulator and the emissivity of the inner wall of the reactor will increase the temperature distribution of the reactor centerline.At the same inlet velocity,the temperature distribution of reactor centerline increases with the increase of working pressure.Under the same working pressure,the temperature distribution of reactor centerline increases with the increase of inlet velocity.The research results have certain reference significance for reactor parameter optimization and thermal stress analysis.
