Propagation of small perturbations in a vapor-gas-droplet system
Abstract
Certain acoustic characteristics of vapor-droplet and vapor-gas-droplet mixtures are identified. In particular, it is shown that the dependence of the attenuation coefficient on the mass concentration of the suspended phase may be nonmonotonic in such mixtures; a criterion for the existence of such a nonmonotonic dependence is presented. Based on the analytical expressions and numerical calculations obtained, it is determined that, at low contents of the suspended phase, heat dissipation may exceed viscosity dissipation due to the relative phase motion.
