球形腔式太阳能吸热器性能的数值研究
Numerical study on the performance of spherical cavity solar receiver
摘要
Abstract
The Monte Carlo ray-tracing method(MCRTM) is used to analyse the optical performance of six spherical cavity receivers with different aperture opening ratio (D/d), and the wall heat flux calculated by MCRTM is used as the thermal boundary condition in the CFD analysis. The fluid-solid coupling heat transfer calculation of the six spherical cavity receivers is carried out by the CFD software.The temperature field of the fluid and wall surfaces is obtained.By calculating the reflection loss,convection loss and radiation loss,it is found that the light-heat conversion efficiency of the concentrator-spherical cavity receivers is between 81.9% and 84.4%.The optimal Dld of spherical cavity receiver is between 1 and 1.5.关键词
