摘要：
In this study,the mechanism of circulation generation in channel with stopexpansion is investigated.The circulation results from the balance between inertia force andbed-induced shear stress.Accordingly,the convective inertia term and the bottom resistance inthe momentum equation are essential to the simulation of circulation.By means of acorresponding 2-D model,the velocity fields of unsteady circulating are computed.Acomparison of the results with the velocity fields measured data is made and the agreement issatisfactory.
