Acoustic waves in multifraction gas suspensions in the presence of phase transformations
Annotation
The propagation of acoustic waves in gas mixtures with vapor, monodisperse drops, and solid particles of various materials and sizes has been studied. A mathematical model is presented; the dispersion relation, the equilibrium and frozen speeds of sound, and low- and high-frequency asymptotes for the linear attenuation coefficient are deduced; the dispersion curves are calculated. The influence of particle size and disperse phase parameters on dissipation and dispersion of acoustic waves is analyzed for a mixture of air with vapor, water drops, and aluminum and carbon black particles. Fast Fourier transform is used to calculate the pulse perturbations in the studied media.
