Flat Plate Boundary Layer By-Pass Transition by Joint Action of Surface Roughness and External Turbulence
Original language description
Flat plate boundary layer by-pass transition by joint action of surface roughness and external turbulence is investigated. The transition process is promoted by both free-stream turbulence and surface roughness. Two independent methods for transition region identification are suggested giving the similar results in various situations. The method of determination of the instantaneous values of wall friction on smooth and rough surface is suggested. The distribution of intermittency factor is evaluated from records of the instantaneous values of wall friction. Estimations of onset and the end of the transitional region from intermittency factor are compared with those from distribution of skin friction coefficient.
