Mach Wave and Acoustical Wave Structure in Nonequilibrium Gas - Particle Flow

Gas-particle flows became relevant in Aerospace Engineering owing to small solid particle additives to alleviate acoustical instabilities in solid propellant rocket motors, thereby motivating the study of a variety of nonlinear and linear waves. Emphasis is placed on fundamental aspects of the relaxation nature of the flow processes.
