Applying lattice Boltzmann method (LBM) to large eddy simulation (LES) of flow around airfoil at low Reynolds number

In the introduction of the full paper, we point out that LBM^[3] is highly promising for application to LES of flow around MAV (micro air vehicle) airfoil, which has characteristics such as incompressibility, low Reynolds number and unsteadiness. Section 1 briefs the LBM. Section 2 explains how we combine LES with LBM to simulate the flow. Section 3 briefs the treatment of curved boundaries. Section 4 calculates the lift and drag properties of NACA0012 airfoil at the angle of attack of zero degree and 10⁵ Reynolds number; the calculated results, given in Figs. 4, 5 and 6, and their analysis demonstrate preliminarily that LBM-LES method is effective for calculating the characteristics of unsteady flow around MAV airfoil.
