摘      要：Acoustic manipulation is one of the well-known technologies of particle control and a top research in acoustic *** of acoustic radiation force on a particle nearby boundaries is one of the critical tasks,as it approximates realistic ***,it is quite difficult to solve the problem by theoretical method when the boundary conditions are *** this study,we present a finite element method numerical model for the acoustic radiation force exerting on a rigid cylindrical particle immersed in fluid near a rigid *** effects of the boundaries on acoustic radiation force of a rigid cylinder are analyzed with particular emphasis on the non-dimensional frequency and the distance from the center of cylinder to each *** results reveal that these parameters play important roles in acoustic manipulation for particle-nearby complicated rigid *** study verifies the feasibility of numerical analysis on the issue of acoustic radiation force calculation close to complex boundaries,which may provide a new idea on analyzing the acoustic particle manipulation in confined space.
