An understanding of the behavior of bubbles in the refining processes is of essential importance because the bubbles affect the quality of steel significantly. Many investigations have been carried out to reveal the behavior of bubbles. Most of them are concerned with bubbles rising away from the wall of the reactor. Information on the behavior of bubbles rising near a poorly wetted wall is very limited, although this bubble rising situation is often encountered in the real refining processes. In this water model study the width and thickness of a bubbling jet formed along a poorly wetted flat plate vertically placed in a water bath are measured in addition to a mean size and a mean rising velocity of bubbles.
