Propagation of spherical and cylindrical waves in multifraction polydisperse gas suspensions

The propagation of plane, spherical, and cylindrical waves in multifraction gas mixtures with polydisperse inclusions has been studied. We have taken into account that the fractions in a mixture differ in their thermophysical properties, inclusion size, and size-distribution functions. A unified dispersion relation is obtained. The evolution of the pressure pulse perturbation in a studied medium is calculated. We show the effect of heat exchange on the attenuation of a pulse perturbation of the pressure in a polydisperse gas suspension.
