AB Results of the numerical calculation of the transonic viscous flow around the supercritical RAE 2822 airfoil are given. The numerical simulation was carried out on the basis of the solution of Reynolds-averaged Navier-Stokes equations enclosed using a Coakley two-parameter differential model of turbulence [1]. For the numerical solutions, a method based on the Godunov-Kolgan-Rodionov explicit difference scheme [2−4] and an EWT-TsAGI packet of application programs [5] was used. The computational studies of the airfoil were carried out to evaluate the accuracy of the numerical method. The coefficients of aerodynamic forces, pressure contours, distribution of the coefficient of friction drag, velocity profiles, and displacement thicknesses are given. The effects of the characteristic value of the velocity pulsations *q*, characteristic frequency of turbulent pulsations *w*, and the number of cells in the computational grid are discussed. The calculations have been carried out for several Mach numbers and are compared to classical experimental results [6] and calculation data [7−11].
