内容記述 | An advanced Large Eddy Simulation (LES) technique with high accuracy and resolution is proposed. This method solves compressible 3-D Navier-Stokes equations with the Approximated Deconvolution Method approach as LES approach and has several sophisticated techniques such as highly tuned compact schemes, the generalized characteristic interface conditions, and the generalized Navier-Stokes boundary conditions. Several applications to flows around 2-D NACA0012 aerofoil are presented and discussed. Numerical results show that this method can solve very complicated subsonic flow including the laminar flow separation at the leading edge region, the transition in the bubble and the reattachment. It also has capability to capture the natural laminar to turbulent transition phenomena in the order of Reynolds number of 10(exp 6). In order to validate the present LES technique in more detail, the results are compared with existing wind-tunnel experiments and linear stability analyses with the e(sup N) method and discussed. | |||||
