| The vortex flow which follows intense sound propagating in a bubbly liquid, is considered. The reasons for acoustic streaming are both nonlinearity and dispersion. That makes streaming especial as compared with that in a Newtonian fluid. Conclusions concern the vortex flow induced in a half-space by initially harmonic or impulse Gaussian beam. The vortex flow recalls a turbulent flow with increasing in time number of small-scale vortices in the vicinity of the axis of a beam's propagation. |
