摘要
耦合因子的计算是空间辐射制冷器热分析的基础 ,蒙特卡洛法是满足抛物面W型辐射制冷器耦合因子计算的有效方法。基于统计原理 ,蒙特卡洛法计算空间辐射制冷器耦合因子的缺点是计算时间较长。通过避免传统的迭代计算 ,加快了蒙特卡洛法计算速度。同时 ,采用改进辐射能束概率分布算法的蒙特卡洛计算精度同传统方法相当 ,并也随随机能束数的增加而提高精度。
The calculation of coupling factors is the key of the thermal design of space radiant coolers and the Monte Carlo method is an effective method to calculate the coupling factors of the elliptical W type space radiant cooler.Beased on the pinciple of statistics,the disadvantage of the Monte Carlo method is the long calculating time.How to avoid iterative calculation of the point emission to accelerate the Monte Carlo method is the focal point in this paper. At the same time ,the improved method has the same accuracy as the traditional method,and the accuracy depends on the increase in sample packet number.
