Abstract

At present, the simulation scheme of grid strategy parameters at hypersonic speed is a hot topic and can be applied to the NACA0012 airfoil, but the selection criteria for Reynolds number and aspect ratio near impact are relatively few, and further research is needed. In this paper, using the NACA4 digital generator airfoil modeling method, a two-dimensional outflow field based on the sharp trailing edge NACA0012 is established. Simulation calculations obtain the numerical results. Through comparison with the reference data, a grid strategy parameters simulation scheme is presented. Unlike blunt bodies, the longitudinal and transverse ratios between cell Reynolds number and cells near impact should be no greater than 16 and 240, respectively.
