A numerical method for moving and deformation grid in the three dimensional flow is developed The arbitrary Lagrangian-Eulerian method is employed. The scheme is fourth-order accurate in space and uses the momentum equations for the velocity coupled to a Poisson equation for the pressure. The fourth-order consistent scheme and 2nd order Adams-Bashforth method are applied to the convective terms in the Navier-Stokes equation. In this investigation, the flow around periodic bending flat plate is computed. We present numerical results, which demonstrate that the controlled actuation of the caudal fin and release of vortex to the efficient production of inverse Karman vortex street.
