| Abstract: | The process of spanwise propagation of turbulence in a laminar boundary layer on a plate is numerically investigated. Three well-known turbulence models are considered. It is shown that the calculated values of the "turbulent wedge" angle are several times less than that observed experimentally. The reason for the deviation of the calculated and experimental data is analyzed. Moscow, Seattle.
