This study aims to investigate the possible application of Dimpled Vortex Generators (DVGs) on aerodynamic surfaces. The study was carried out under the VPP Sports Project (National Research Program: Sports), supported by the Latvian Ministry of Education and Science, with the goal of improving sports technology in the field of aerodynamics. Golf ball is a classic example of surface roughness leading to aerodynamic improvement due to delayed boundary layer separation. Inspired by the dimpled surface of a golf ball, in this study, the investigation takes on the approach of finding an optimized dimple design based on shape (semi-spherical, square, and triangular), size, and placement along the chord of a small wing segment. The aerodynamic performance of each DVG configuration was compared using CFD against the smooth baseline wing section (without DVGs). The results showed a significant improvement in the drag coefficient with a drop of up to 27% and a 36% increment in the lift-to-drag ratio in the semi-spherical DVG configuration. Contrarily, square and triangular DVGs demonstrated lower aerodynamic enhancement compared to semi-spherical ones.
