The time step is in the order of 10 microseconds. Initially there is a total of 64 elements and 41 nodes on the bubble surface. Additional elements are inserted as the bubble grows to keep the resolution roughly the same. Normally, its final size is much greater than its initial size and the number of elements on the bubble surface is in the order of 1,500 and the number of internal nodes is in the order of 800. Typical Results Bubble formation under cross-flow configuration.
Time unit is millisecond.
Detached bubble radius as a function of the ambient liquid velocity under different gravitational effects. The We number increases from 0.058 to 1.274 along with the increase of the liquid velocity.
