In this article, the applicability of the cumulant lattice Boltzmann method (CuLBM) to simulate boundary layer flow above rough surfaces is investigated. The fluid is assumed to be incompressible and Newtonian and its flow is investigated under isothermal conditions above surfaces with small obstacles. The results obtained by the CuLBM are confronted with the results of a reference finite difference-based simulator and with the datasets from wind-tunnel experiments. Both comparisons indicate good agreement and suitability of the lattice Boltzmann method for these types of problems.

粗糙表面上方湍流的累积格子Boltzmann模拟

在本文中，研究了累积格子玻尔兹曼方法（CuLBM）在粗糙表面上模拟边界层流动的适用性。假定流体是不可压缩的牛顿流体，并且在等温条件下具有较小障碍物的表面上研究了流体的流动。CuLBM获得的结果与基于参考有限差分的模拟器的结果以及风洞实验的数据集相对。两种比较都表明格子Boltzmann方法对于这些类型的问题具有良好的一致性和适用性。
