Abstract: | A method of statistical modeling the flow in the boundary-layer transition region is proposed on the basis of experimental
data on kinematics and dynamics of turbulent spots (Emmons spots) on a flat plate in an incompressible fluid. This method
allows one to determine the intermittency with allowance for overlapping of the spots, the forces on the plate surface, and
the flow field in the vicinity of the transition region if the field of the streamwise component of the mean velocity in the
developed turbulent boundary layer is known as a function of the Reynolds number. In contrast to multi-parameter models of
the transition, this approach makes it possible to avoid the use of physically meaningless parameter values. |
