Closed Loop Control and Turbulent Flows

Abstract

Theoretical modelling and experiments were conducted with a goal towards reducing skin friction in a turbulent channel flow. We developed closed loop adaptive feedforward algorithms, as well as actuators and sensor systems for implementation in a turbulent channel. Significant progress was made in theoretical controller development. Actuators were successfully fabricated and characterized, and open loop performance was demonstrated, although more research is required to complete the closed loop experimental part of the program.
