REFLECTION OF ACOUSTIC WAVE FROM THE BOUNDARY OF A TWO-FRACTION POLYDISPERSE GAS SUSPENSION

The problem of normal incidence of an acoustic wave on the interface between a pure gas and a gas suspension is considered. The case of gas suspension consisting of two fractions, each of which is polydisperse and is described by a certain size distribution function of inclusions has been studied. The dependences of the phase velocity and refl ection coeffi cient on the frequency of perturbations are calculated. The infl uence exerted by the size distribution function of inclusions, as well as by the mass content on inclusions of the dependences of the refl ection coeffi cient on the frequency of perturbations has been established.
