Scattering coefficients for a sphere in a visco-acoustic medium for arbitrary partial wave order
journal contribution
posted on 2020-06-08, 10:49 authored by M Mahbub Alam, Valerie PinfieldValerie Pinfield, Pierre MaréchalAnalytical solutions are reported for the scattering coefficients of a solid elastic sphere suspended in a viscous fluid for arbitrary partial wave order. Expressions are derived for incident compressional and shear wave modes, taking into account the viscosity of the surrounding fluid and resultant wave mode conversion. The long compressional wavelength limit is employed to simplify the derivation, whereas no restriction is placed on the shear wavelength in the fluid compared to the particle dimension. The analytical approximations are compared with numerical results obtained from matrix inversion of the boundary equations and agree within the validity domain of the solutions.
