SIMULATION OF PERIODIC VORTICAL STRUCTURES IN THE AIRFOIL WAKE
摘要
Parametrical calculations of an unsteady flow around a NACA 0012 airfoil at a fixed Reynolds number of 40,000 are performed using several multi-block overlapping grids of different scales and densities, which cover settlement areas of various extents, including the near and far wakes. The solutions found by Menter's shear stress transport model, the Spalart−Allmaras vortex viscosity transport model, and the method of vortical domains, are compared with available estimated and experimental data. Verification of the two-dimensional model is performed by comparison of the numerical predictions for a cross flow over a thick plate with Igarashi's experimental data.
