Abstract: Based on the moving least squares corrected smoothed particle hydrodynamics (SPH) method,a moving boundary problem model has been simulated.A forced revolving moving boundary particle treatment is presented.The principal of the corrected SPH and its correction-step are introduced.A fixed boundary model is also constructed and separately simulated by the corrected SPH method and the commercial software FLUENT.Comparing the results,it has been shown that the correction approach can smooth the pressure oscillation,and this forced revolving moving boundary treatment is practical and effective.The method can be employed to simulate a more complex model.It has some referential value for the research on moving boundary problems in various areas.
