![]() Dependence of the drag C D and lift coefficient C L on the angle of attack was determined using two different turbulence models. The aim of the work was to find out the optimum turbulent model out of two models b y showing the behavior of the airfoil at specified conditions and to establish a verified solution method. The flow was obtained by solving the steady-state governing equations of continuity and momentum conservation combined with any two turbulence models aiming to the validation of these models through the comparison of the predictions and the free field experimental measurements for the selected airfoil.
