Shock Structure and Relaxation in the Multi-Component Mixture of Euler Fluids

The shock structure problem is studied for a multi-component mixture of Euler fluids described by the hyperbolic system balance laws. model developed in framework extended thermodynamics. Thanks to equivalence with kinetic theory approach, phenomenological coefficients are computed from linearized weak form collision operator. Shock analyzed three-component polyatomic gases, and various combinations parameters (Mach number, equilibrium concentrations molecular mass ratios). analysis revealed that mixtures possess distinguishing features different binary ones, certain behavior may be attributed constituents. multi-temperature compared single-temperature one, difference between mean temperatures computed. Mechanical thermal relaxation times along profiles, ones smaller case discussed this study.
