| Abstract: | The module to analysis the propellants slosh in tank of liquid rocket was put forward by the volume of fluid method and arbitrary Lagrangian-Eulerian method in this paper. The general formula was also given. The numerical calculation for nonlinear slosh of propellants in tank with different shape under normal and low gravity was made, and the liquid slosh in tank under micro gravity was done by drop tower test. It was showed that the results of the simulation and test were similar. The calculation method in this paper was applicable in engineering. |
