Simulation of the Laminar–Turbulent Transition by Applying Dissipative Numerical Schemes

The applicability of a low-order monotone shock-capturing scheme to the simulation of the laminar–turbulent transition is demonstrated. The laminar–turbulent transition is simulated in a supersonic boundary layer over a flat plate at a Mach number of 3. The numerical results are compared with results of other authors based on low-dissipative schemes. The spectral characteristics of disturbances in the linear and nonlinear development regions, the structure of the transient flow, and averaged boundary layer characteristics are compared.
