  • Based on the distributed parameter numerical model of cryogenic propellant tank, pressurization of a LO2 tank pressurization system during engine firing was simulated by employing the liquid rocket engine test-bed modularization modeling and simulation software-gas system(LRETBMMSS-GS).The simulation results agree well with test data and experiential correlation prediction,which shows that the distributed parameter tank model is more accurate and comprehensive than lumped parameter model in describing flow and thermal stratification phenomena in cryogenic tank.Accordingly,the numerical system of finite volume model and corresponding simulation software have a wide applicability and good simulation precision,which are valuable and can be developed further in pipe system simulation field.
