ABSTRACT
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.

    The small angle scattering of radiation or particles from many porous solids may be described in terms of fractal geometry. To date most examples have been surface fractals but a few studies have suggested that some porous solids may be mass fractals. We give a derivation of the scattering law...
