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 this paper, the VOF method is used to simulate the liquid sloshing caused by the rocket engine shutdown. Taking the oxidant tank as an example, the shaking simulation diagram and liquid mass center curve of the tank without damping ring and damping ring are obtained. The VOF method was tested for its ability to handle broken waves.
