[Abstract]:In order to solve the problem that the excited outlet flow model can not realize the full-field simulation of synthetic jet, a numerical simulation method of three-dimensional synthetic jet flow field based on moving grid is proposed. In this method, the local reconstruction algorithm of moving grid is introduced. By inserting the compiled user-defined function program to define the moving mode of the grid in the common numerical simulation method of the flow field, the dynamic grid region related to the motion of the grid is set up. The flow field of a three-dimensional synthetic jet is solved under the periodic sinusoidal motion of the vibrating film. The experimental results show that this method is feasible to obtain the characteristic flow phenomenon of jet nozzle and the corresponding law of nozzle velocity change.
