| Abstract: | The propagation of acoustic waves in the two-fraction mixtures of gas with vapor, droplets, and solid particles of different
materials and sizes with phase transformations has been studied. Nonstationary and nonequilibrium effects of the interphase
exchange of the impulse, mass, and heat have been taken into account. A system of the differential equations of the motion
of the mixture has been presented, and the dispersion relation has been deduced. The high- and low-frequency asymptotics of
the attenuation coefficient have been obtained and analyzed. The effect of the heat and mass exchange on dispersion and dissipation
of acoustic waves in the two-fraction mixtures of gas with vapor, droplet, and solid particles has been studied. |
