Surface phenomena in a three-dimensional skewed shock wave/laminar boundary-layer interaction

Abstract

A parametric study of the three-dimensional skewed shoc k wave/laminar boundary-layer interaction has been performed at a Mac h number of 2.25. The data indic ate a great similarity in the behavior of the laminar and turbulent interac tions. In parlic ular, they both exhibit a région of conical flow and satisfy similar upstream influence corrélations. A study of the behavior of the flow wilh increasing shock strengths has led to the hypothesis of a graduai évolution of the flow structure.

Dynamics of dual-pulse laser energy deposition in a supersonic flow

“…For the validation of the model, we took the experimental data from [25], where the authors studied a flow field and surface pressure distribution for the laminar supersonic flow around wedges at Mach number M = 2.25 having different incidences α with respect to the freestream. The calculated and measured surface pressure distributions are shown in figure 2 for in the pressure distribution but also showed a good quantitative agreement.…”

“…We used the first-order implicit Euler scheme for the discretization of the temporal term and a second-order unbounded scheme for the advection terms, which limits the upwind scheme in the regions with strong gradients. A secondorder central difference scheme was chosen for diffusion terms A comparison of numerical results with experiment [25] for the axial pressure distribution of flow over a wedge for a high speed flow. and mass fluxes.…”
