Supersonic Boundary Layer in Regions with Small Temperature Perturbations on the Wall
The problem of disturbed flow in the laminar boundary layer when heating elements are located on the surface is investigated. The flow is described by the theory of viscous-inviscid interaction with full Navier–Stokes equations. We apply the triple-deck model of the flow and describe asymptotic multiscale structure for the supersonic case. Using this structure as a base, we construct the solution to the flat stationary problem by means of Fourier transform and analysis in the complex plane. It is also shown that localization of a heating element may arrive at a singularity of the pressure downstream. Results of numerical and analytic analysis are presented. Using these elements gives us the opportunity to develop a novel method for the separation control of the boundary layer.
Steady subsonic boundary layer in domains of local surface heating
Abstract The perturbed flow in a laminar boundary layer is investigated when there are heating elements on the body surface. The flow is assumed to be laminar and subsonic everywhere. It is shown that such flows can be described within the scope of free interaction theory. A solution of a plane steady-state problem is constructed in the linear approximation. The results of analytical and numerical analysis are presented.
