High Reynolds number mathematical models for convected vortex impinging against a local hump and sound scattering into Tollmien–Schlichting eigenmodes are introduced to simulate basic mechanisms of the disturbance excitation typical of turbomachine

In this paper we explore essentially nonlinear disturbances produced in an incompressible boundary layer by a roughness on the wall. The scale of the stationary roughness is supposed to be large enough so that generated waves are governed by the forc

The triple-deck theory to describe boundary-layer free interaction and separation is carefully investigated from the viewpoint of how it predicts stability properties of a viscous flow. The linearized version of this theory gives the same results as

An extended version of the triple-deck theory is developed for high Mach number subsonic and transonic flows, assuming the Reynolds number to be large enough. The theory embraces unsteady spiral-type Gortier vortices on a concave surface and vortical

Absolute instability of (Gortler vortices on the severely curved concave pressure side of a gas-turbine blade is the main thrust of the third-year work under this grant. For the most part, the Gortler vortices have been investigated in an incompressi

Recent theoretical findings show that the curvature of streamsurfaces naturally warping in the crossflow direction of a three-dimensional boundary layer can maintain centrifugal forces, provoking unsteady short-scaled vortices. The wave/vortex eigenm
