Question: Consider the in viscid flow of air past the rounded equilateral triangle shown in the accompanying figure. Perform numerical experiments by changing the velocity of the upstream air and the r/L. ratio (for r/L = 0,r//L = 0.1, and r/L - 0.25) and obtaining the corresponding air velocity distributions over the triangle. Discuss your results.
