Non-Linear Waves in Gas Dynamics and Mechanics

Abstract

Nonlinear wave propagation in gas flows, MHD, combustions, elasticity, multiphase flows etc. is studied. Shock waves which are either more or less compressive than the classical gas shocks are shown to be nonlinearly stable, but in the sense distinct from each other. This resolves the longstanding paradox on their physical admissibility by pointing out the sensitive role of dissipations. The phenomenon of non-equilibrium is systematically studied. The problem of zero relaxation limit is resolved for models in mechanics and phase transition. Nonlinear wave propagation, Mechanics, Gas dynamics.
