摘要: 文章给出了载人航天器生活舱传热传质的数学模型及边界条件 ,对微分控制方程运用基于有限元网格的控制容积法来离散 ,对离散后的代数方程使用欠松弛的高斯 -塞德尔(G -S)迭代法求解 ,最终得到了舱内流场、温湿度场的数值分析结果。

Abstract: The mathematical model and boundary conditions of heat and mass transfer in a manned spacecraft habitation cabin are given at first. Then finite-element grid based control volume method is used to discrete the governing equation. The SUR based Gauss-Seidel point iteration method is applied to solve the entire algebraic equation set. Finally, the numerical analysis results of the cabin's flow/temperature/humidity distribution are obtained.
