A DSMC (direct simulation Monte Carlo) simulation using Dynamic Molecular Collision (DMC) model and Multi-Stage (MS) 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 are obtained behind the leading edge over the plate. Pressure, heat flux ratio on the plate in the DSMC results agree well with those in the experimental results. The results also indicate that the effects of gas-surface interaction are revealed not only in the macroscopic states but also in the microscopic states.
