摘要

Reynolds-averaged Navier-Stokes equations along with the Spalart-Allmaras one-parameter differential turbulence model are applied to investigate the unsteady flow over airfoils. The pressure and friction coefficient distributions on the airfoil surface, Mach number contour lines, numerical schlieren photographs, as well as the values of the aerodynamic coefficients are presented. The influence of the flow structure on the aerodynamic characteristics is analyzed. A map of the transonic turbulent flow regimes around the NACA 0012 airfoil on the plane free-stream Mach number angle of attack is composed.
