Title

CFD Analysis of controlling the airflow over airfoils using dimples

Abstract

Aircraft aerodynamic’s primary goal is to boost the aircraft's aerodynamic qualities and manoeuvrability. Reducing the drag-and-stall phenomenon would naturally improve aerodynamic capabilities. This research is an attempt to improve airfoil's aerodynamic properties by adding several dimple-shaped surface modifications. The dimple form we chose is triangular in nature. We put 12 dimple numbers in both surfaces with 12 in the upper and 12 in the lower surface. The dimples were placed in a convenient location such that the creation of the boundary layer could be postponed. Typically speaking the dimple generates instability by generating vortices which in effect slows the forming of the boundary layer. Dimple pressure drag is decreased with the application and the sound effects are also minimized. This research involves the dimple effect on aircraft wing numerical analysis using NACA 0018 airfoil with uniform cross section along the airfoil range.
