Based on papers from the 2004 NASA/ONR Circulation Control Workshop, this collection is an invaluable, one-of-a-kind resource on the state-of-the-art in circulation control technologies and applications. Filling the information gap between 1986 - when the last such symposium was held - and today, it summarizes the applications, experiments, computations and theories related to circulation control, emphasizing fundamental physics, systems analysis and applied research. The papers presented cover a wide variety of aerodynamic and hydrodynamic applications including naval vehicles, fixed-wing aviation, V/STOL platforms, propulsion systems and ground vehicles. Anyone with interests in applied aerodynamics, fluid mechanics and aircraft design will find this book of particular value, as will those seeking a an up-to-date reference work on circulation control and its many current applications.
