Herein, the pressure-sensitive paint (PSP) was used to quantitatively investigate aerodynamic effect of an alula-like vortex generator, which is a bio-inspired passive flow control structure. The global pressure distributions on upper surface at different angles attack were measured determine strength sectional suction forces wing. An generator equipped leading edge wing enlarged area region (n...

A wind turbine is a device that converts mechanical energy into electrical by its rotary action. In this paper, turbine’s lift and power characteristics are improved employing vortex generator as passive flow control on the surface of turbine. triangular used for study simplicity in design effective results. NACA 4418 airfoil selected conceptual BEM (Blade Element Momentum theory), geometrical ...
