Small perturbations in the chemically active gas medium with the reversible reaction and external energy source and reagents source

Small acoustical perturbations in the stationary non-equilibrium chemically active gas medium with the reversible chemical reaction and external energy source and reagents source are considered. For the investigated model of the non-equilibrium medium the basic thermodynamical and acoustical characteristics are defined, dispersion relation are obtained, the numerical and parametrical analysis of the acoustical instability is performed. The obtained results for the investigated model of the non-equilibrium medium have been compared with the analogous results for other models of the non-equilibrium mediums.
