Abstract: | The nonlinear interaction of acoustic and entropy modes in a bubbly liquid is considered. The reasons for interaction are
both nonlinearity and dispersion. In the field of intense sound, a decrease in the mixture density is predicted. That corresponds
to the well-established growth of bubbles volumes due to rectified diffusion. The nonlinear interaction of modes as a reason
for a bubble to grow due to sound, is discovered. The example considers variation in the mixture density and bubbles radii
caused by acoustic soliton. |
