Abstract
The triple-deck analysis of boundary layer flow over topography is extended to include the effects of stable stratification in the free-stream. Analysis of the linearized three-dimensional flow shows that gravity waves generated in the outer region have a significant influence on the flow in the boundary layer due to the interactive nature of the triple-deck structure. Numerical solution of the two-dimensional nonlinear equations shows the inhibition of separation by the stratification, and also gives larger amplitudes of the generated gravity waves than would be expected from the linearized theory.Keywords
