Test particle Monte Carlo simulation for return flux due to ambient scatter of outgassing molecules on a circular disk
针对航天器工作中的返回流污染问题,利用试验粒子 Monte Carlo(Test Particle Monte Carlo,TPMC)方法对圆盘表面出气分子形成的环境散射返回流进行数值模拟,验证了计算结果与相关研究的一致性。结果表明:返回通量比随圆盘表面半径、来流气体速度、来流气体分子数密度的增加呈线性增大;随出气分子质量、来流气体攻角的增加而先增大后减小;随出气表面温度的增加而减小并渐趋于稳定;随来流气体分子质量的增加而增大并渐趋于稳定;随来流…查看全部>>
Considering the return flux contamination problem in spacecraft operation,the re-turn flux on a circular disk surface due to ambient scatter of outgassing molecules is simulated using the Test Particle Monte Carlo(TPMC)method.Results about the return flux(RFR)ob-tained here are in good agreement with the references.Some factors affecting the return flux are analyzed.Computational results show that the RFR increases linearly with the increase of the ra-dius o…查看全部>>
