具有增强碰撞和静止粒子的格子玻尔兹曼方法用于计算二维盖驱动腔中的流动。通过计算解析解已知的测试问题，验证了该方法计算具有狄利克雷和诺依曼边界条件的几何结构中不可压缩流体的速度和压力的能力。已针对从 $Re=10$ 到 $Re=2000$ 的雷诺数测试了不同的参数配置。已经针对各种纵横比研究了具有不均匀最高速度的更广义的盖驱动腔问题的涡流结构。
The lattice Boltzmann method with enhanced collisions and rest particles is used to calculate the flow in a two-dimensional lid-driven cavity. The abilitity of this method to compute the velocity and the pressure of an incompressible fluid in a geometry with Dirichlet and Neumann boundary conditions is verified by calculating a test-problem where the analytical solution is known. Different parameter configurations have been tested for Reynolds numbers from $Re=10$ to $Re=2000$. The vortex structure for a more generalized lid-driven cavity problem with a non-uniform top speed has been studied for various acpect ratios.
