密度锁内流体分层界面下移情况的相关研究

Research on Movement of Fluid Stratification Interface in Density Lock

分析了密度锁内流体分层界面形成的原因,建立了一个简单的力学模型解释界面下移的原理,通过实验数据验证了这一原理;并通过实验验证了栅格形状、栅格尺寸、扰动大小和温差因素对界面下移速度的影响。结果表明:四种因素中栅格尺寸和温差对界面下移速度有影响,栅格小通道截面面积越小,界面下移越慢;温差越大,界面下移越慢。

The cause for the formation of fluid stratification interface was analyzed,and a simple mechanical model was founded to interpret the principle of interface movement. The effects of the grid shape and size,the disturbance magnitude and temperature difference on the interface removal speed was validated experimentally. The results indicated that only the grid size and temperature difference had effect on the interface movement speed. The smaller the channel sectional area was and the larger temperature difference was,the more slowly the interface moved.
