Skin-friction measurements and computational comparison of swept shock/boundary-layer interactions

Physical model of the swept shock wave/boundary-layer interaction flowfield

“…Although measurements of surface pressure, skin friction, 3 and surface behavior 4 have all led to a greater understanding of these interactions, the structure of the interaction flowfield has been comparatively poorly understood.…”

Advances in CFD prediction of shock wave turbulent boundary layer interactions

“…Table 14. Experimental data of Zheltovodov et al [143,154] and Kim et al [158] is available for Cases 1,3 and 2, respectively. The computations were performed at the same flow conditions as the experiment.…”

“…Knight [157] concluded that the pitot pressure, yaw angle and surface pressure are predictable with reasonable accuracy using algebraic or two-equation turbulence models, however the surface heat transfer is not accurately predicted in strong interactions. In the particular case of the sharp-fin/plate configuration, Kim et al [158] have performed a joint experimental and computational study of skin friction in weak-to-strong interactions at M ∞ = 3 and 4. In their Navier-Stokes calculations they tested algebraic turbulence models and the k− model, integrated to the wall or employing the wall-function technique.…”

“…One of the sharpfin/plate flows examined by Kim et al [158] was used as model. After the validation of the results, by comparison with appropriate experimental data, he studied the flowfield by means of stream surfaces which start at the inflow plane, within the undisturbed boundary layer, and which are initially parallel to the plate.…”

Investigation of Three-Dimensional Shock Wave/Turbulent-Boundary-Layer Interaction Initiated by a Single Fin

“…However, due to the nature of strong non-equilibrium flow in 3D SWTBLI, especially when the state of the reverse flow could possibly change during the process, numerical simulation based on Reynolds-averaged Navier-Stokes (RANS) equations with standard turbulence models is not very reliable for this kind of flow. [3,[21][22][23] Panaras [24,25] has pointed out the inadequacy of the Boussinesq's equation in predicting strong cross-flow separation generated in the fin/plate configuration. Reviews of numerical predictions of 3D SWTBLIs with existing turbulence models were recently carried out by Knight et al [3] , Zheltovodov and Knight [20] , and Panaras.…”
