Nonclassical Transonic Boundary Layers: Toward Overcoming Dead-End Situations in High-Speed Aerodynamics

Resumo

Analytical models of unsteady free viscous-inviscid interaction of gas flows at transonic speeds, i.e., a transonic boundary layer with self-induced pressure (nonclassical boundary layer) are considered. It is shown that an adequate flow model can be constructed by applying methods of singular perturbations. The results of a comparative analysis of classical and regularized stability models for a boundary layer with self-induced pressure in the case of interaction at transonic speeds are overviewed.
