| 摘 要： | Lattice Boltzmann方法是近十年来发展起来的基于介观层次上的新算法,是一个崭新的求解流体系统偏微分方程的行之有效且效率比较高的数值计算方法,以其为物理现象建模的手段,在很多领域得到了应用,尤其在化工领域中具有复杂边界和复杂流场的模拟中取得巨大成功,如湍流、多孔介质流、化学反应流、燃烧模拟、结晶过程、磁流体等等。采用LB方法中的D2Q9模型,采用BGK碰撞模型及BounceBack边界条件数值模拟流体在顶盖驱动中的流动现象,给出流场的流线和等压线图,计算结果表明该方法运用到顶盖驱动流动计算中,所得结果与基准解吻合良好。 |

| Abstract: | Lattice Boltzmann method is a new theory developed in recent years.This method is based on the Kinetic theory.Using D2Q9 model and BGK approximation the Cap-driven flow had been simulated under different Re,flow pattern and isobar had been got under different Re.The results showed that use of the Lattice Boltsmann Equation to simulate Cap-driven flow were in good agreement with the benchmark solutions. |
| Keywords: | Lattice Boltzmann method simulation cap-driven flow BGK model D2Q9 model |
