The attenuation of shock waves in a nonequilibrium gas

The evolution of weak shock waves in nonequilibrium gas media with fluctuating parameters is investigated. Two-dimensional nonlinear, evolution equations are derived for the averaged parameters of an acoustic field induced by a body in a supersonic flow of active medium. A possible mechanism of redu...

Zusammenfassung:	The evolution of weak shock waves in nonequilibrium gas media with fluctuating parameters is investigated. Two-dimensional nonlinear, evolution equations are derived for the averaged parameters of an acoustic field induced by a body in a supersonic flow of active medium. A possible mechanism of reduction of the amplitude and broadening of the front of weak shock waves in nonequilibrium gas media is discussed.
