| 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. |
