Research on Movement of Fluid Stratification Interface in Density Lock

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.
