Theoretical calculation of the acoustic radiation force acting on elastic and viscoelastic cylinders placed in a plane standing or quasistanding wave field

摘要

In this work, a new expression of the acoustic radiation force function Y-st for solid cylindrical targets, suspended in inviscid fluids in a plane standing wave field, is presented. The case of a plane quasistanding wave field is also considered. Numerical calculations of the radiation force function Yst are performed in a wide range of frequencies for elastic and viscoelastic cylinders and compared to those of rigid cylinders. The fluid-loading effect on the radiation force function curves is also analysed. The results show several features quite different from the rigid cylinder solution.
