在轨贮箱内气液分布特性极大影响箱内压力变化,为了提高主动控压技术的效率,延长推进剂在轨储存时间,开展微重力下低温推进剂贮箱内气泡运动及融合特性的研究至关重要。本文采用流体体积函数法模拟微重力条件下低温推进剂贮箱内单个不同尺寸氧气泡的运动以及多个随机分布氧气泡的融合过程。结果表明:10
-5
g微重力条件下,随着贮箱内氧气泡半径增大,氧气泡所受浮力以及上下面的压强梯度越大,上升一定距离所需时间缩短;当氧气泡的半径小于100 mm时,氧气泡在释放后一段时间内最大速度小于10
-4
m/s
基本处于停滞状态,并且停滞时间随着氧气泡半径的减小而增长;当不同尺寸氧气泡上升时,即便有部分氧气泡半径小于100 mm
仍能在多个力场的综合作用下,缓慢上升并发生碰撞与融合,聚集于贮箱顶部,形成了稳定的椭球回转体形状的“气枕”构型。本文研究结果证明“气枕”集中模型假设是可行的。
