摘要
Interaction of the submerged vortices with a progressive surface wave was investigated by the finite difference numerical solution of Navier-Stokes equations. The progressive wave was the surface gravity water wave in a finite depth. The initial vortex model is Oseen vortex. The numerical computations show that a special pattern of water wave surface may be observed by the interaction of the submerged vortices. The influences of Froude number, the initial geometric configurations of vortices, and the amplitude, initial phase of surface wave on the wave pattern were discussed.
