摘要： 为确定通道式表面张力贮箱的通道数,通过分析最差工况下液体所覆盖的筛网面积,给出了通道宽与接触面积关系图和湿润圆位置与最小接触面积的关系图,在10-2g加速度下贮箱采用1个横向通道和5个沿g g轴周向环布的通道较为合适。计算结果可为通道式表面张力贮箱的优化设计提供参考。

Abstract: Based on the relationship between the channel width and the minimum screen area covered by the pool under the worst operating condition, the number of the channels was chosen. The relationship between the location of the pool and screen area covered were presented. The result obtained can provide a reference for the optimization design of the channel surface tension tank.
