The Effects of Viscosity on the Structure of Shock Waves in a Non-Ideal Gas

This work presents the structure of viscous shock front in a non-ideal gas. The analytical expressions for the particle velocity, temperature, pressure and change-in-entropy within the shock transition region are derived taking into consideration the Landau and Lifshitz equation of state for non-ideal gas. The effects on the structure of shock front due to the variations of the coefficient of viscosity, Mach number, adiabatic exponent and parameter of non-ideality of the gas are investigated. The model developed in the paper is valid only for small values of Mach number M i.e., M < 2.5.
