The Control of a Thin Free Shear Layer with and without a Semi-Infinite Plate by a Pulsating Flow Field
A general solution for the fluctuations of a plane and infinitesimally thin shear layer excited by an exterior forcing motion is given. Incompressibility of the fluid and symmetry of the boundary conditions at both sides of the boundary layer are assumed. Two configurations are considered: A free shear layer extended from − ∞ to + ∞, and a free shear layer starting from a semi-infinite plate. In the latter case one finds forced oscillations caused by external excitation only. New closed form solutions for some special cases are given.
