| Abstract: | The program of gas replacement in the tank is drawn up with C# NET software. The influence of different filling pressure and final pressure after deflation of nitrogen and hydrogen on gas replacement in the tank is analyzed with the program. An optimum scheme of gas replacement is determined by comprehensive comparison. The numerical calculation of gas replacement process in the liquid hydrogen testing tank of a rocket engine power system is carried out with FLUENT software. The numerical calculation includes the nitrogen filling replacement, hydrogen filling replacement, downsizing scaling and full-size liquid hydrogen tank. The results of numerical calculation are compared with the replacement of existing liquid hydrogen tank on the test-bed. The duration time of the gas mixing uniformity after completion of the hydrogen filling is calculated. |
