摘要
本文首先根据U.Frisch等人所提出的格子气FHPⅡ模型的要点,建立了该模型的完备的微观动力学(碰撞规则)。在此基础上,对一种CVD问题的简单模型进行了格子气仿真。文中介绍了边界条件和初条件的处理,以及在微机上实现仿真的分段算法。
The first part of this paper gives complete collision rules for FHP Ⅱ 7-bits model of lattice gas automata. Some of them are irreversibe, them are different from the extension given by other authors.The second part is an example computed by the LGS method. Initial and boundary conditions are treated appropriately A random method is to ensure the conservation of the total particles number with a little stochastic fluctuation. Macro-velocitis are got through averaging over a time interval and smoothing on space. The results are in good agree ment with the classical concepts.
