Single Bubble on Flat Plate

It is of practical importance to predict the shape and size of such a bubble just before detachment from the cylinder. If the cylinder is immersed in a still water bath, the shape and size of a bubble in contact with it can be accurately predicted

Very little is iaiown about the effects of wettability of a plate on bubble and molten metal flow characteristics except for the frequency of bubble formation, /b [20-22], These studies have shown that the frequency of bubble formation from a single-hole nozzle or a porous nozzle that is not wetted by the liquid is significantly different from that from a single-hole nozzle of good wettability. This result suggests that the bubble and liquid flow characteristics near a vertical flat plate would...
