| Abstract: | In this paper the integral equation of the boundary layer momentum thickness is derived, in which the curvature and rotation terms are considered.It is shown that the curvature and rotation have direct effects onthe structure of the turbulence. A menthod of correction for the calculation of the velocity distribution in the turbulent boundary layer is presented. |
