摘要：
We investigate propagation of acoustic waves in gas mixtures with fractions of various materials and size particles. We propose a mathematical model; obtain the dispersion relations, the equilibrium and the frozen sound velocity, and the lowand the high-frequency asymptotes of the linear attenuation coefficient; and calculate the dispersion curves. We also analyze the influence of the particle size and the disperse phase parameters on the acoustic wave dissipation and dispersion for a multifraction gas suspension with sand, aluminum, and sand particles. The calculation results are compared to the experiment.
