Evaluation of an analysis method for low-speed airfoils by comparison with wind tunnel results

R. Evangelista, C. VEMURU

Open publisher page 6 citations

Abstract

Results obtained by the airfoil analysis method of Drela (1980) for three airfoils are compared with wind tunnel test results. The method is shown to be accurate in predicting the aerodynamic characteristics of low-speed airfoils in the chord Reynolds number range from 200,000 to 3 million. It is noted that a high value for the transition criterion was necessary to accurately study the case of laminar separation.
