  • To simplify the grid generation procedure in aeroacoustic problem simulation and develop a computational scheme suitable for moving complex geometries,a strategy of guaranteeing the impermeable boundary condition based on the immersed boundary(IB) method was proposed in the paper.Simulations of sound radiation from moving bodies were performed with relatively simple motion.Satisfactory comparison was conducted between present computational data and theoretical solutions,verifying the feasibility of the present method.
