摘要
本文采用 VOF方法对火箭发动机关机阶段所引起的液体晃动进行了数值仿真 ,以氧化剂贮箱为例 ,得到了贮箱无阻尼环和带阻尼环时的晃动仿真图和液体质心变化曲线。检验了 VOF方法处理碎波的能力。
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.
