摘要：

采用动量转换方法,应用格子Boltzmann模型计算流体对边界的作用力，用二维六角形的格子Boltzmann模型计算沟槽形状边界的Coutte流动,得出沟槽形状边界的阻力。计算结果显示,沟槽形状边界的阻力系数随Re数的增大而减小,其变化规律与平板边界的情况一致。

关键词: 格子Boltzmann方法;沟槽形状边界的Coutte流;阻力系数

Abstract:

Using the momentum exchange method, the Lattice Boltzmann model was adapted to calculate the force acting on the boundary. The two dimensional hexagonal Lattice Boltzmann model was used to simulate the Couette flows with the sawtooth boundary and evaluate the drag coefficient of the sawtooth boundary. The result indicated that the variation of the drag coefficient vs Reynolds number was the same as that of the plane boundary.

Key words: Lattice Boltzmann method;couette flow with a groove boundary;drag coefficient
