|A paper and movie about a rising bubble. Imagine an air bubble rising in water, a thermal of hot air rising on a cold day, or smoke rising out of smokestack. In each case, the interface between the two fluids will change dramatically as the fluids move. As an example, consider a bubble of a fluid of one density, initially circular, and rising in a fluid of a heavier density. Although the bubble starts off circular, as it rises it accelerates in the middle, and the sides are caught up in a pair of swirling vortices.|
