Enhancement Of Aerodynamics Of Airfoils By Surface Modifications – Numerical Study
Kline-Fogleman Airfoils, Stall Angle, Lift, Drag.
Abstract— the present work focuses on surface modification over airfoil to enhance its aerodynamics. The modification being considered here is the right angled triangle, inspired by the Kline-Fogleman Airfoil (KFm Airfoils). This outward dimple acts as a vortex generator and delays the boundary layer separation of flow and thus increases the stall angle and the lift of the airfoil. The surface modification was done on the cambered four digit NACA 4415 airfoil. The two dimensional airfoil was analyzed with and without dimples using a CFD software. The simulations were performed using the k-ε turbulence model. The dimples were placed at three different chordwise location and were simultaneously compared with the smooth airfoil
