摘要

本文介绍了低温推进剂在轨管理中热力学排气系统（thermodynamic venting system，TVS）的构成及工作原理。基于VOF模型，编写用户自定义程序考虑箱内存在的热质传递现象，采用CFD模拟贮箱内部的压力变化和温度场分布。构建的CFD模型能够较好地模拟TVS的工作特性，证明CFD研究的有效性。针对不同液体初始充灌率、节流条件等影响因素进行变工况模拟，揭示TVS的工作规律。计算TVS在微重力下的控压性能，验证其在微重力下的可行性并获得运行规律。

Abstract

This article described the composition and working principle of the thermodynamic venting system (TVS) for the in-orbit management of cryogenic propellants. Based on the volume of fluid (VOF) multiphase model

a user-defined function (UDF) was compiled to consider the heat and mass transfer phenomena inside the tank

and computational fluid dynamics (CFD) was applied to simulate the pressure evolution and temperature field distribution in the tank during the TVS operation. A comparison study showed that the CFD model could well simulate the characteristics of the TVS

which might verify the effectiveness of the CFD approach in analyzing TVS performance. Moreover

the variable conditions of different initial liquid filling rate

throttling ratios

and other influencing factors were simulated to reveal the working rules of the TVS. The pressure control performance of the TVS under microgravity was also calculated. The feasibility of the TVS under microgravity was verified

and its operational rules were obtained.
