전산유체역학을 이용한 태양열 화학반응기에서의 열전달 특성 해석

초록

This paper describes the experiment and simulation results of a heat transfer in the SCR (solar chemical reactor). The SCR is installed on the dish type solar collector, Inha Dish-1 in Songdo, Incheon. Dish type solar collector which has operation temperature above 1000℃ is normally classified in high temperature process in solar thermal engineering. With this high operation temperature, convective heat loss, thermal fracture are important features for designing SCR. In this paper, temperature distribution of the SCR is measured and compared with simulation result. SCR is made of SUS304 and the receiver diameter is 10cm and 6 sheets of 10mm thickness porous metals are laminated inside the receiver. Irradiation from Inha Dish-1 is about 5kW. Simulation result and measured temperature shows similar inclination through the center line of the SCR.
