【Abstract】 In the present paper,the Volume Of Fluid(VOF) method is employed to simulate the slosh of liquid in container during the period of shut down of the rocket numerically.As an example,the slosh of the oxidizer has been simulated and a series of the simulation figures have been plotted in both cases of the container with/without damping ring.The investigation shows that VOF method has a powerful capability even to deal with the problem as the free surface breaking up.更多还原
