Multiple translational temperature model and its shock structure solution.
Within a shock layer, the translational motion of the gas is more energetic in the direction perpendicular to the shock front than in the direction parallel to the shock. To predict this translational nonequilibrium, a generalized gas-kinetic BGK model is proposed. With the adaptation of a continuum gas distribution function truncated up to the Navier-Stokes order and a generalized particle collision time, this newly constructed kinetic model is used in the monatomic gas shock structure calculations, where two translational temperatures inside the shock layer are well captured.
