Flow Topology of Symmetric Crossing Shock Wave Boundary Layer Interactions

Large-Eddy Simulation of a Three-Dimensional Hypersonic Shock Wave Turbulent Boundary Layer Interaction of a Single-Fin

“…The agreement of the skin friction coefficient between LES and measurement is satisfactory except for the corner region, where the stiff incease of Cf and its peak value meansured in the experiment are under-predicted. The under-prediction of Cf in the corner region can also be found in other numerical simulation researches [15,38] . The reason for this is still not clear and due to the limitation of the skin friction measurement data namely in 3D SWTBLI, the calibration of CFD method will be quite difficult.…”

“…Due the employment of the sponge layer in all the three direction, the size of the effective domain, which is marked with red line in Figure 1 . The present computational domain is similar with that of the experimental measurement of Schulein [10] , and the RANS study of Salin et al [15] , which is convenient for direct comparisons.…”

“…Comparing with the two-dimensional (2D) SWTBLI with a homogeneous transversal direction, the three-dimensional (3D) SWTBLI is less studied and understood, although, it is closer to real flows and has special influences on the performances of intakes and control surfaces. [2][3][4][5][6][7][8][9][10] Most researches of 3D SWTBLI are limited in the framework of experimental measurements and numerical simulations by solving Reynolds-averaged Navier-Stokes (RANS) equations [11][12][13][14][15] . The large-eddy simulation (LES) or direct numerical simulation (DNS), which can give detailed information of turbulent flows and greatly benefits the research of turbulence mechanisms, has not been applied in the 3D SWTBLI yet in published reports.…”
