Acoustic radiation force due to incident plane-progressive waves on coated cylindrical shells immersed in ideal compressible fluids

In this paper, a theoretical analysis is developed for the acoustic radiation force due to incident plane progressive waves on elastic cylindrical shells covered with a layer of viscoelastic and sound-absorbing material. Numerical calculations of the radiation force function Y-p (which is the radiation force per unit energy density and unit crosssectional surface) are performed in a wide range of frequencies with particular emphasis on the coating thickness and the content of the hollow space region of the shells. Various methods for damping resonance peaks, such as by changing the fluid that fills the interior hollow region of the shells or the coating thickness, can be carefully selected for various applications.
