基于本课题组先前工作提出的多尺度过程界面耦合重构算子,本文将该重构算子用于格子-Boltzmann方法(LBM)和人工压缩方法(ACM)耦合计算中,提出了基于多尺度重构算子的LBM和ACM界面耦合方法。为检验该耦合方法,将其用于模拟二维顶盖驱动流,数值结果表明LBM与ACM耦合方法可以正确模拟非稳态流动问题,并能有效地提高计算速度。 Based on the multi-scale process interface coupling and reconstruction operator presented in our previous work, this paper uses the reconstruction operator in the lattice-Boltzmann method (LBM) and manual compression method (ACM) coupling calculation. Based on multi-scale Reconstruction of LBM and ACM interface operator coupling method. In order to test this coupling method, it is used to simulate the two-dimensional canopy driving flow. The numerical results show that the LBM and ACM coupling method can simulate the unsteady flow problem correctly and can effectively improve the computational speed.
