二维直角弯道中粘性流动的格子气体仿真

Lattice Gas Simulation of 2-D Viscous Flow in a Right-Angled Bend

本文应用具有完备碰撞规则的格子气自动机,对二维的直角弯道中的粘性流动进行了仿真,给出了在计算机计算能力限制下。解决这个问题的具体方法及初步的计算结果。结果表明,仿真出来的流场,在总的流动趋势、涡旋以及分离现象上,较好地再现了真实流动。

This paper deals with the lattice gas simulation of 2-dimensional viscous flow in a rightangled bend, based on the complete collision rules of FHP-Ⅱ 7-bits model. The lattices used are about 4000, but the results are still in good agreement with the classical concepts.
