Abstract:
Stability of a supersonic $(\mathrm{M}_\infty=5.373)$ boundary layer with local separation in a compression corner with a passive porous coating partly absorbing flow perturbations is considered by solving two-dimensional Navier–Stokes equations numerically. The second mode of disturbances of a supersonic boundary layer is demonstrated to be the most important one behind the boundary-layer reattachment point. The possibility of effective stabilization of these disturbances behind the reattachment point with the use of porous coatings is confirmed.
Keywords:
Navier–Stokes equations, supersonic flows, boundary layer, stability, numerical simulation, porous coatings.
