Flow Control

This work covers passive as well as active, including reactive, flow control systems. Sophisticated reactive control systems heavily relying on parallel computers are envisioned for practical devices to improve the ability to reduce drag, increase lift, and achieve other flow control goals.

The potential benefits of realizing efficient flow-control systems range from saving billions of dollars in fuel costs for air, sea and land vehicles, to achieving economically/environmentally more competitive industrial processes involving fluid flows. The understanding of some basic mechanisms in free-shear and wall-bounded turbulence suggests that the taming of turbulence is possible so as to eliminate some of its deleterious effects while enhancing others. Passive as well as active, including reactive, flow control systems are covered. Sophisticated reactive control systems heavily relying on parallel computers are envisioned for future practical devices to improve the ability to reduce drag, increase lift, suppress flow-induced noise, enhance mixing and achieve other desired flow control goals.
