The effect of the combustible gas component on the propagation and damping of perturbations in bubbly mixtures is analyzed. For describing the propagation of acoustic perturbations in a liquid with bubbles containing combustible gas component itis possible to employ a one-velocity, two-pressure model of the medium that takes into account the radial inertia of the liquid with change in the volume of the medium. The liquid carrier phase is assumed to be compressible, and the changes in bubblevolume are described within the framework of a spherically symmetric model using the equation of the radial pulsations of the bubble. For simplification we introduced effective viscosity for taking into account heat dissipation. It is shown considerableeffect of admixtures, such as chemical energy release due to the presence of a combustible gas component, on the interphase heat exchange in gas-liquid media, as well as on the phase velocity and attenuation of sound in bubbly mixtures.
