Abstract:

The work is devoted to a study of the phenomenon of boundary layer transition on a parabolic wing profile. Particular attention is paid to an investigation of the effect of blunting of the wings leading edge as well as the effect of a single Re number on the transition of a laminar boundary layer to a turbulent one. An attempt was made to explain the reason for the influence of the degree of blunting of the leading edge on the transition region.
