Unsteady Flows

3 Credits

This course examines the forces and flows that arise when rigid or flexible objects produce unsteadiness in a surrounding flow. The concepts of added mass and circulatory forces, hydrodynamic impulse, and vortex force are introduced. Unsteady forces of maneuvers and wing-gust encounters are examined with classic theories such as Theodorsen, and von Kármán and Sears. Unsteady numerical panel methods are introduced. Unsteady flows produced by bluff bodies and oscillating bodies are discussed.
