102 極超音速希薄流における並進・回転エネルギーの微視的状態 : 気体分子衝突モデルの影響(O.S.1-1 希薄流)(O.S.1 電子・イオン・分子の流れ)
詳細
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.
