Large Eddy Simulation of Transition and Full Turbulence in A Compressible Boundary Layer

摘要：

A spatial Large-Eddy Simulation (LES) is conducted to investigate the characteristics of the supersonic/ hypersonic boundary layer transition and full turbulence flow. Some cases were numerical simulated to attain the specific turbulence coherent structure and the mean flow parameters. Hybrid methods of a fifth-order upwind compact difference and a sixthorder symmetric compact difference were used to numerically solve the three-dimensional compressible nondimensional Favre-filtered Navier-Stokes equations. The compact storage third-order explicit Runge-Kutta method is applied for time-integration. The sub-grid scales (SGS) are formulated according to the modified Smagorinsky eddy-viscosity model. The computational results are agreed well with the relevant theory and experiment data.
