Numerical Analysis of Joukowski (T = 12%) Airfoil by k-ε Turbulence Model at High Reynolds Number

Abstract

In aerodynamics, the role of an airfoil is vastly dominant to generate the adequate lift to transport the aircraft. Aerodynamically characteristic of an airfoil is construct on the design yet still its desire performance of an airfoil is ground on design yet its result is not simple in present days [1]. In present scenario airfoil design is observe arbitrary for the flows of an aircrafts and a very early time in history Orville and Wilbur brothers made and design camber or asymmetrical airfoil and In before days NACA define a proper way to describe the definition of an airfoil and tells about their characteristics or how airfoil efficient. In present study about NACA4412, NACA0012 and JOUKOWSKI (t = 12%) airfoil, at different Angle of attack and velocity of flow is 43.822 m/s in CFD [2]. The salient feature of present work study is to knows about their behavior of fluid flow located on each and every sides of an airfoil and calculate the characteristics of aerodynamic performances at very high Reynolds Number (3 million) and angle of attacks varies from 2° to 18°. The coefficients of drag and lift for all the airfoil is determined by seeing the surface pressure on different airfoil. In present research work performance of aerodynamics of an airfoil are plot against Angle of attack and how the results area unit getting ready to the experimental results. During this work we have a tendency to calculate and observe the comparison of k-e turbulence model along with experimental results [3].
