Parametric studies of aerofoil-vortex interaction; a numerical approach using LES
Abbreviated Journal Title
The influence of angle-of-attack and vortex-aerofoil vertical miss-distance on the aerofoil-vortex mechanism of interaction is investigated numerically using the large-eddy simulation approach. The study concerns the aerofoil-vortex interaction (AVI) phenomena encountered in the rotorcraft aerodynamics. The studies are performed for a Reynolds number of 1.3 x 10(6) based on the chord (c = 0.2m) of the aerofoil and free-stream velocity U = 100ms(-1). The studies are conducted for three different angles-of-attack (alpha = 0 degrees, and alpha = 5 degrees, alpha = 10 degrees) and vertical miss-distances (h = 0.0m, h = -0.01, h = -0.02m) respectively. The present study shows that the magnitude of lift coefficient and flow separation, at the instant of interaction, decay with the increase of angle-of-attack and vertical miss-distance.
