Fundamentals and Applications of Modern Flow Control

Synopsis:

Modern passive and active flowfield control is a rapidly emerging field of significant technological importance to the design and capability of a new generation of forthcoming air-vehicle systems, spawning major research initiatives in government, industry, and academic sectors of aeronautics. This completely revised two-day short course will address introductory fundamentals as well as several emerging air-vehicle applications of modern aerodynamic flowfield control techniques. The first day will cover a brief overview of the fundamentals of flow control, including basic concepts, terminology, history, strategies/techniques, actuators, sensors, modeling/simulation, and closed-loop control. The second day will cover applications of flow control to current and next-generation air vehicle systems, including vehicle propulsion integration, airfoil control, noise suppression, wake control, and some forthcoming non-aeronautical applications. A multi-institutional team of eight researchers from government, industry, and academia will cooperatively teach this course.

Key Topics:

  • Concepts, terminology, and history of flow control
  • Flow control strategies
  • Actuators and sensors
  • Modeling and simulation techniques
  • Closed-loop flow control
  • Air vehicle applications: Propulsion, Airfoil, Dynamic Flowfield, Non-Aero Apps

Who Should Attend:

The short course is intended for engineers, scientists, graduate students, or managers in industry, government and academia who desire an introductory-level course in the physics and control of aerodynamic and/or fluid dynamic flow fields. The course is suitable for those in fluids related fields such as aeronautics, astronautics, automotive, and processing.
