概要

• 論文の詳細を見る

• This paper presents theoretical and experimental analyses of turbulent boundary layer velocity profiles and the boundary layer parameters. This work clarifies the influence of adverse pressure gradients and the effect of the boundary layer control by uniform suction on the boundary layer. A continuous velocity profile from a sublayer to an inner layer is obtained by developing the damping factor of a mixing length to the boundary layer with suction. The velocity profile in an outer layer is determined theoretically by extending a theory on the assumption of intermittency phenomena at the outer layer with adverse pressure gradient and uniform suction. The results of theoretical calculation are in good agreement with the experimental data.
