Abstract:
The problem of interaction of small hydrodynamic perturbations with a nonequilibrium region in a gas flow with different models of energy pumping is solved. One-dimensional and two-dimensional interactions are considered. A range of system parameters is found in which interaction occurs in a resonant manner (significant amplification of perturbations is observed). It is demonstrated that interaction of vortex perturbations with the nonequilibrium region generates heat waves.
