Numerical Analysis of the Acoustic Radiation Force and Acoustic Streaming Around a Sphere in an Acoustic Standing Wave

A numerical scheme has been developed to calculate the acoustic radiation force and streaming for spherical objects in a standing wave. A combination of multipole series expansion and Stokeslet method is implemented for the calculations. The scheme was verified by comparing its results with those obtained from the analytical solution, proposed by Doinikov (1994). Unlike the analytical solutions, the proposed numerical scheme is applicable to the case of multiple spheres in a viscous fluid.
