Description
Laminar separation bubbles (LSB) are thought to be responsible for the performance degradation of airfoils, especially in the relatively low Reynolds number regimes of interest to UAVs and MAVs. A rough picture of the fluid dynamics of LSB is as follows. A steady laminar flow over an airfoil separates from the surface as it encounters an adverse pressure gradient The separated laminar shear layer is inviscidly unstable due to the presence of an inflection point in the velocity profile, and thereby the Tollmien-Schlichting waves are amplified upstream of the separation point as noted by Diwan and Ramesh1. The laminar shear layer quickly transitions into
