摘要

抛物面屏是G型辐冷器的主要制冷部件之一，蒙持卡洛法计算其与各辐射表面之间耦合因子的关键是正确模拟计算随机辐射能束的发射位置与发射方向。对于抛物面屏这种立体曲面截面，提出新的算法正确模拟计算随机辐射能束的发射位置与发射方向。通过扩展抛物面屏曲面，删除抛物面屏外的辐射能束，筛选初次模拟辐射能束，解决了发射位置的模拟计算。通过切平面坐标与原辐冷器坐标变换，将切平面辐射能束的发射方向变换坐标系，解决了发射方向的模拟计算。以上述算法为基础，蒙特卡洛法淮确计算了G型辐冷器抛物面屏对各表面的耦合因子，并对计算结果进行了误差分析。

Abstract

The parabolic reflector of the G-type radiant cooler is one of the most important refrigeration parts

and the key point of calculating its exchange factors to other parts by the Monte Carlo method is to simulate the location and direction of radiant packets correctly. This research found new methods to confirm the location and direction of energy packets on the curved surface during calculating exchange factors of the parabolic reflector of the G-type radiant cooler. By expanding the curved surface and screening out first simulating radiant packets

valid radiant packets filter through the boundary of the parabolic reflector and are able to confirm the location correctly. By exchanging tangent plane coordinate system to original coordinate system

the direction of radiant packets is confirmed by radiant packets generated from tangent plane of the parabolic reflector. Depending on new methods

exchange factors of the parabolic reflector to other surfaces are calculated by the Monte Carlo method and results are analyzed too.
