Abstract

This paper focuses on aerodynamic analysis over a 3D cambered wing with dimple-like surface modification. Application of the golf ball dimples on airfoils is predicted to be a good alternative for drag reduction. A golf ball with dimples allows for smooth and controlled flight. Models of cambered wings based on NACA 2412 airfoil were created to investigate the dimple effect. A comparative study is carried out between wing models with inward and outward dimples at 50% of chord length locations. Simulations were conducted for two velocities – 30 m/s and 90 m/s and the angle of attacks varying from 0° to 20°. The study is carried out using different platforms for respective processes. Firstly, ANSYS WORKBENCH© and SOLIDWORKS© are used for the geometry creation of the wing model. Next, ANSYS FLUENT© is used for the pre-processing and solver setup stage. Then, TECPLOT©, MATLAB© and FLUENT© are used for the post-processing and analysis stage. The inward dimple showed better aerodynamics when compared with outward dimple and no dimple cases.
