Calculation of Spatial Heat Flux Based on Improved Monte Carlo Algorithm
摘要
空间热流计算是空间目标热特性及红外特性分析的基础, 针对传统蒙特卡洛法在计算空间目标热流时存在耗时较多的不足, 提出了基于图形加速的改进的蒙特卡洛热流计算方法, 并分别采用传统算法和改进算法计算了卫星的太阳热流, 数值分析表明改进算法在保证同等计算精度的前提下, 显著提高了卫星太阳热流的计算速度。
Abstract
Calculation of spatial heat flux is the base of analysis of spatial targets’ thermal character and infrared feature. In view of time-consuming problems in calculating the spatial heat flux which exist in the traditional Monte Carlo algorithm, the improved Monte Carlo algorithm based on graphics acceleration is put forward. The satellite solar heat flux is calculated respectively by traditional algorithm and improved algorithm. And numerical analysis shows that under the premise of the same calculation accuracy guaranteed, improved algorithm significantly improves the calculation speed of satellite solar heat flux.
