摘要: 本文计算Frish-Hasslecher-Pomeau(缩写为FHP)模型的平均自由程λ。计算表明,当粒子碰撞超过60次后λ趋于常数;当粒子密度为0.25时λ取最小值,对应于雷诺数的最大值。此外,本文还指出FHP模型与分子动力学模型的某些差别。

Abstract: The mean free path of the FHP hydrodynamical models is calculated. The calculations show that the mean free path is approximate to a constant after more than 60 collisions and is a minimum, which is corresponding to the maximum of Reynolds' number, when particle density is 0.25. In addition, the difference between the FHP models and the molecular dynamic models is showed clearly.
