本文提出了格子玻尔兹曼方法与大涡模拟相结合来模拟高雷诺数下的流体流动。高雷诺流数值模拟中采用亚网格模型作为大涡模拟模型。子网格模型的思想基于包含未解析运动对已解析流体运动的物理影响的假设。它采用简单形式的雷诺应力涡粘模型。格子玻尔兹曼方程中的升力和阻力评估采用曲面体动量交换法。首先，本数值方法在低雷诺数下得到验证。其次，采用开发的格子玻尔兹曼方法/大涡模拟方法来解决高雷诺数下的流动问题。进行了一些详细的定量比较以显示本方法的有效性。实验证明，格子玻尔兹曼方法结合大涡模拟模型可以有效地模拟高雷诺数流动。
Lattice Boltzmann method combined with large eddy simulation is developed in the article to simulate fluid flow at high Reynolds numbers. A subgrid model is used as a large eddy simulation model in the numerical simulation for high Reynolds flow. The idea of subgrid model is based on an assumption to include the physical effects that the unresolved motion has on the resolved fluid motion. It takes a simple form of eddy viscosity models for the Reynolds stress. Lift and drag evaluation in the lattice Boltzmann equation takes momentum-exchange method for curved body surface. First of all, the present numerical method is validated at low Reynolds numbers. Second, the developed lattice Boltzmann method/large eddy simulation method is performed to solve flow problems at high Reynolds numbers. Some detailed quantitative comparisons are implemented to show the effectiveness of the present method. It is demonstrated that lattice Boltzmann method combined with large eddy simulation model can efficiently simulate high Reynolds numbers’ flows.
