Abstract This investigation initially focuses on the study of dimple effects on an airfoil. Application of the golf ball dimples on airfoils is predicted to be a good alternative for drag reduction as per the concept of flow separation for a golf ball. A NACA series airfoil is selected, and a comparative study of the boundary layer thickness is made between a dimpled and a smooth design. The mesh discretization is carried out holding the “Law of wall” true, for an accurate simulation of the boundary layer. The results are compared with the available experimental data. Calculations were performed to predict the optimized location and curvature of the dimple to achieve a change in the aerodynamic efficiency. A rumored application of a similar concept is possibly being applied on the Boeing 787-9 in the form of a hybrid laminar flow control. However, there are no reliable sources to confirm it.
