Laminar flow over a small unsteady three dimensional hump
Abstract
The effect of a small three dimensional hump (whose shape varies some way in time) on an incompressible boundary layer is studied, using extensions to triple deck theory, for a number of regimes of unsteadiness. The effects on both two dimensional and three dimensional boundary layers are considered. These results are used to consider the interaction between a boundary layer and a small vibrating panel, situated on an otherwise flat surface.
