用概率型模型测量格子气的粘性系数
MEASUREMENTS OF VISCOSITY OF A LATTICE GAS USING A PROBABILITY MODEL
-
摘要: 在Boltzmann假设下,提出一种概率型格子气模型,并通过对平面Poseuille流的模拟,用数值方式“测量”了格子气体的粘性系数。数值结果同理论上得到的解析粘性系数进行了定量比较,得到了非常符合的结果。

Abstract: A probability type lattice gas model is proposed,using Boltzmann approxi-mation. Kinamatic shear viscosity of the lattice gas is mesured by numerical simulation ofPoiseuille flow.Quantitative comparison of the numerical results with theoritical ones areshown, they are in good agreement. -
