Abstract
The steady vortex induced by the flow supplied from tangential direction withdrawn through a hole at the center of the bottom of a vessel is considered. And the flow due to the eccentric sink is added to these vortex flow is also considered.
The purpose of this paper is to elucidate the fundamental feat-ures of the flows of these two types. By using hydrogen bubbles method as visualization technique, the flow characteristics was visualized, and compared between the two types.
