摘要
本文提出了格子-Boltzmann方法的一种新的插值算法,使得网格划分与微观粒子运动方向相分离;用该方法 模拟了后台阶通道内的突扩流动和二维极坐标下的空腔流。所得结果与传统方法吻合良好,证明了该方法的可行性。
In this paper, we proposed a new interpolation strategy, where the computational grid and the momentum lattice are two different mesh systems, and the density distribution function can be calculated by interpolation. Using this strategy, we simulated the flow in a 2D symmetric sudden expansion channel and the lid driven cavity flow in polar coordinates The results agree well with the traditional method, indicating the feasibility of this strategy.
