Abstract
Lattice Boltzmann Method (LBM)是一种近年来发展的基于分子动理论的数值方法，它具有计算简单、边界易于处理的特点。本文基于采用D2Q9模型的LBM方法对NACA0012翼型进行了数值模拟与分析，数值结果表明：对于简单翼型的低雷诺数、非定常湍流流场，LBM方法的数值结果与CFL3D参考值可以很好的吻合。因而，该方法对于低雷诺数下简单翼型流场计算是一种有效的计算手段。 Lattice Boltzmann Method (LBM) is a numerical method based on molecular dynamics theory de-veloped in recent years. It has the characteristics of simple calculation and easy boundary treat-ment. In this paper, the flow with low Reynolds number for NACA0012 airfoil were analyzed and simulated based on LES method with D2Q9 model. The numerical results show that the numerical results of the LBM method fairly agree with the reference value of CFL3D for the low Reynolds number and the unsteady turbulent flow field of the simple airfoil. Thus, this method is effective for calculating the wing flow field at low Reynolds number.
