Numerical simulation of the evolution of unstable disturbances of various modes and initial stages of the laminar turbulent transition in the boundary layer at the freestream Mach number M 6
Direct numerical simulations of linear and nonlinear stages of the evolution of unstable disturbances of various modes and initial stages of the laminar turbulent transition in the boundary layer on a flat plate at the freestream Mach number M 6 are performed on the basis of full unsteady Navier Stokes equations for a compressible gas. A considerable effect of three dimensional unstable disturbances on initiation of the laminar turbulent transition is demonstrated.
