Abstract: This study presents the feasibility of trapping vortex inside a cavity for various low aspect ratio wing configuration as a passive control mechanism. The vortex formation flow structures were investigated qualitatively at low Reynolds number of 26,000 at angles of attack of 0°, 5°, 10° and 15°. Three wing configurations were manufactured which consist of a solid wing model without any cavity, a wing model with a single cavity and a wing model with triple cavities. A smoke wire technique was employed to visualize the flow. The results revealed that the wing with cavity generally managed to trap stable vortex in a clockwise direction. The flow remained attached and delayed separation at high angles of attack compared to the non cavity wing model configuration. Triple cavities wing configuration has a higher vortex intensity which has the potential to enhance lift and ultimately improve the aerodynamic performance.
