CFD Modelling and Analysis of Clark Y Airfoil for Turbulent Flow

Airfoils have taken their rightful place as one of the most integral components in the field of aerodynamics. Every kind of airfoil has its own particular design and significant characteristics which must be studied and analysed before subjected to the implementation of an actual flight. Several aerodynamic effects concerning lift, drag, velocity and pressure were evaluated by subsonic wind tunnel testing and computational fluid dynamic method in order to determine the behaviour of Clark Y airfoil (11.7% smoothed). Furthermore, the difference of results achieved by the two methodologies of subsonic wind tunnel testing and computational fluid dynamics were compared. In this paper, an analysis was performed at an air velocity of 18.77 m/s and 0.05 Mach (turbulent conditions) to derive and study the sensitivity of meshing, coefficient of lift, coefficient of drag, lift to drag ratio, pressure, velocity and vector profile of Clark Y airfoil.
