102 Microscopic State of Translational and Rotational Energy in Hypersonic Rarefied Gas Flow : Effects of Gas-gas Collision model
Details
A DSMC (direct simulation Monte Carlo) simulation using Dynamic Molecular Collision (DMC) model based on Molecular Dynamics (MD) calculation is applied for solving the two-dimensional nonequilibrium hypersonic rarefied flow over a flat plate with angle of leading edge. Numerical results show that nonequilibrium between translational and rotational temperature is obtained behind the leading edge over the plate. Translational and rotational energy distributions in the nonequilibrium flow show a typical distribution which is significantly different from the Maxwell-Boltzmann distribution, and reveal a transition process from the nonequilibrium state to the equilibrium state.
