Analysis of Flow Characteristics Around an Inclined NACA 0012 Airfoil Using Various Turbulence Models

Abstract
The current paper presents a computational fluid dynamic analyses of the flow characteristics over an inclined NACA 0012 airfoil using various turbulence models at Mach number of 0.13. The primitive continuity and momentum equations were solved using Ansys-Fluent in turn along with Spalart-Allmaras, Realizable k – ε, and k – M shear stress transport. The response of pressure and velocity contours, lift coefficient (Cl) and drag coefficient (Cd) to inclination angle variation from – 14° to 20° are reported. Also, the values of Cl and Cd obtained from the current work were juxtaposed with the equivalent values of experimental data gotten from earlier work done by Abbott and Von Doenhoff and the comparison showed good agreement. Furthermore, the results revealed that stalling occurred between 14° and 16°.
