Abstract of the paper ``Effective constants for wave propagation through
partially saturated porous media'' with Lewis Thigpen
The multipole scattering coefficients for elastic wave scattering from a
spherical inhomogeneity in a fluid-saturated porous medium have been calculated.
These coefficients may be used to obtain estimates of the effective macroscopic
constants for long-wavelength propagation of elastic waves through partially
saturated media. If the volume average of the single scattering from spherical
bubbles of gas and liquid is required to vanish, the resulting equations
determine the effective bulk modulus, density, and viscosity of the
multiphase fluid filling the pores. The formula for the effective viscosity
during compressional wave excitation is apparently new.
