Question: Consider the inviscid flow of air past a NACA symmetric airfoil. Abbot and Von Doenhoff (1959) provide detailed information about NACA symmetric airfoil shapes, including geo-metric data for NACA symmetric air foils Using their geometric data, obtain the velocity distribution over the NACA 0012-airfoil shown in the accompanying figure. Perform numerical experiments by changing the angle of attack and obtaining the corresponding air velocity distributions over the airfoil. Discuss your results.
