Assessment of several modeling strategies on the prediction of lift-drag coefficients of a NACA0012 airfoil at a moderate Reynold number

This paper investigates modelling strategies on the prediction of lift and drag coefficients of a NACA0012 airfoil at Reynolds number of 360,000. Two computational methods are employed; namely Navier-Stokes equation and panel method, by using different tools for computing lift and drag coefficients....
