抄録

The behaviour of bubble plumes were studied in both a linear and a two-layered stratification. When bubbles were released downward flow formed outside the inner upward plume induced by bubbles, and different types of intrusions formed from the downward flow depending on the relationship between the stratification intensity and the bubbling rate. The inner plume's fluid diffuses outwards only in the zone where the downward flow exists.<br>The inner plume entrained the surrounding water and increased in size up to the critical level at which the drag force exerted by the bubbles is balanced with the negative buoyancy of the inner plume.<br>The efficiency of the input energy conversion to potential energy increases at first, shows peak, then decreases with increasing bubbling rate and decreasing stratification intensity.
