摘要
建立了具有石英窗口的太阳能高温吸热器的能量传递与转换模型，采用谱带辐射传递因子描述太阳光与热辐射能束的传输特性。结合谱带模型，通过蒙特卡洛射线踪迹法模拟，得到谱带辐射传递因子。在此基础上，分析了太阳能高温吸热器的热转换特性，考察了石英窗口的光学性能参数与吸热芯温度分布对太阳能高温热转换的影响，获得了对太阳能高温吸热腔设计有参考价值的结果。
An energy transfer and conversion model for the high temperature solar energy receiver with a quartz window has been developed, in which the transporting behavior of solar energy and that of thermal radiation were described by the spectral radiation distribution factors. The Monte Carlo ray-tracing method in combination with the spectral band model was employed to simulate the radiative transfer within the system to obtain those factors. The thermal conversion characteristics of high temperature solar energy receiver were analyzed, and the effects of optical properties of quartz window as well as the temperature distribution of energy absorber were discussed. Some valuable results for the design of solar energy receiver were obtained.
