Abstract

On the basis of a numerical solution, by the finite-volume method, of the Reynolds equations closed by means of a two-parameter dissipative model of turbulence the authors refine the mechanism of reduction of the head resistance and achievement of high quality of profiles of large thickness by intensification of the flow in the vortex cells on the contour with account for the influence of the Reynolds number and the angle of attack.
