An investigation of finite wings with leading edge protuberances by Gan, Christopher De Hao

“…In the present study, Particle Image Velocimetry (PIV) was carried out in a water tunnel at a Reynolds number of 2.0 x 10^4 to investigate the cross stream flow around finite wings with leading-edge protuberances. Results obtained confirm that the protuberances lead to the generation of counter-rotating vortex pairs (CVPs), similar to the function of vortex generators. …”
