Acoustic Waves in Multifraction Gas Suspensions with Polydisperse Inclusions
The propagation of acoustic waves in multifraction gas suspensions with polydisperse inclusions has been studied. The disperse phase contains N fractions, which differ in size, the size-distribution functions of inclusions, and materials. The dispersion relation, which determines the dependence of the complex wavenumber on the perturbation frequency, is obtained. The dependences of the relative speed of sound and attenuation coefficient on the dimensionless perturbation frequency are obtained. The effect of heat transfer is analyzed.
