Abstract

The gas within a shock wave lias more thermal energy in the direction perpendicular to the shock than in the parallel direction. This translational non-equilibrium is modeled with newly-developed multiple translational temperature conservation equations. For this representation of the gas, the expressions for the thermal conductivity, viscosity, and rate of translational energy relaxation are developed for a gas with an inverse-power intermolecular potential The model is tested by comparing adiabatic box simulations and computed shock waves to direct simulation Monte Carlo calculations. These comparisons verify the validity of the modeling approach.
