| Summary: | The invention discloses a numerical simulation method for a bubble nonlinear scattering sound field in liquid, and relates to the field of bubble nonlinear scattering sound field simulation. The method solves the problems that the simulation of a bubble nonlinear scattering sound field is realized by combining fluid dynamics and solid mechanics in the prior art, but the method is only suitable for a limited closed area and has insufficient applicability. The method comprises the following steps: S1, constructing a bubble region; s2, constructing a fluid area surrounding the bubbles; and S3, constructing an acoustic propagation domain surrounding the fluid region, and controlling acoustic wave propagation through an acoustic wave equation to complete simulation. The method is applied to the fields of underwater detection, positioning and communication, ultrasonic medicine and the like.
