- 論文の詳細を見る
Large eddy simulation (LES) of compression ramp flow with a shock wave was successfully performed at a free-stream Mach number of 2.9 and a Reynolds number of 10^6 based on the boundary layer thickness. A compressible Smagorinsky-type eddy viscosity model was employed. It was shown that the present LES predicts not only the time-averaged quantities but also fluctuations such as pressure deviation and shock motion near the compression corner. Also, the present simulation predicts the three-dimensional structure of shock/turbulent boundary interaction, which is difficult to simulate by using Reynolds averaged Navier-Stokes equations (RANS).
