摘要

摘要: 从一维可压缩液体的瞬变管流方程出发,采用有限体积法,对液体火箭发动机实验台液路系统工作过程进行了一维数值仿真,并将计算结果与实验结果进行了比较与分析。结果表明,该方法较好的描述了发动机实验台液路系统的工作过程,能为实验台系统的设计、故障诊断、优化以及实验发动机的性能分析提供指导。

Abstract: Starting from the transient pipe flow equation of one dimensional compressible fluid and using finite control volume method,the working process of the fluid piping system for liquid-propellant rocket engine testing was simulated.Through the comparison between calculated data and experimental data,the results illustrate that the method used in this paper describes preferably the working process of the fluid piping for the liquid-propellant rocket engine experiment system and can provide guidance for the design of experiment system,fault diagnosis,optimization and performance analysis of liquid-propellant rocket engine.
