The ability to control and thereby delay flow separation has long attracted considerable interestrnin aerodynamics, as separation leads to a reduction in aerodynamic lift, an increase in aerodynamicrndrag, and consequently a decrease in the overall aerodynamic performance of a body. This phenomenonrnaffects bluff bodies at relatively low Reynolds numbers, as well as slender bodies, such asrnaerofoils, at higher Reynolds numbers.
