Abstract

The rotational nonequllibrium effect is taken into account by introducing excess normal stress associated with the bulk viscosity of the gas. The computational model for diatomic gases reduces to the model for monatomic gases in the limit of vanishing bulk viscosity. The thermodynamically consistent computational model is applied to the one-dimensional shock wave structure and the two-dimensional hypersonic rarefied flow around a blunt body in order to demonstrate its capability and validate the numerical results.
