Abstract
Fluid dynamics and dynamics of two-dimensional airfoils as well as bluff bodies are studied in presence of the Moving Surface Boundary-layer Control (MSBC) using wind tunnel tests, numerical finite element analysis and flow visualization. Results suggest significant increase in the maximum lift coefficient and delay in the stall for airfoils, and decrease in the drag for bluff bodies. The concept proved effective in suppressing vortex resonance and galloping type of instabilities encountered by tall buildings, bridges, smokestacks and similar bluff structures.
