Chapter 9, Problem 9-74(choose chapter or problem)
Steady, incompressible, two-dimensional flow over a newly designed small hydrofoil of chord length c 5 9.0 mm is modeled with a commercial computational fluid dynamics (CFD) code. A close-up view of flow streamlines (contours of constant stream function) is shown in Fig. P974. Values of the stream function are in units of m2/s. The fluid is water at room temperature. (a) Draw an arrow on the plot to indicate the direction and relative magnitude of the velocity at point A. Repeat for point B. Discuss how your results can be used to explain how such a body creates lift. (b) What is the approximate speed of the air at point A? (Point A is between streamlines 1.65 and 1.66 in Fig. P974.)
