ABSTRACT
In a tilted surface, the buoyancy of the developing bubble creates the drifting force parallel to the surface, changing the detachment mechanism and consequently the size of emerging bubbles [3]. If a bubble drift out of the orifice by the surface component of buoyancy, it means that buoyancy did not reach the critical level to detach the bubble from the surface. Therefore, in such a case, the drifted bubble does not detach from the surface by buoyancy, and the detachment occurs, if it occurs, by another force that didn’t encounter the horizontal surface. In the absence of other forces, the drifted bubbles often do not detach from an inclined surface; instead they keep marching on the inclined surface until the end of the surface where tow bubbles collide and form a larger bubble, whose buoyancy is large enough to detach the merged bubble.
