概要	The 2D driven cavity flows are often utilized as benchmark solutions. Extensive studies have been done on the steady and unsteady flows. However, the behavior of unsteady flows at high Re and flows in deep or shallow cavities are not fully understood. For example, Poliashenko and Aidun (abbreviated as PA in the following) predicted that the Hopf bifurcation changes its kind as the aspect ratio is larger than or smaller than 1. In the present study, we focus our attention to the effect of aspect ratio B=width/height, or A=height/width on the critical Re.
