The Impact of the outlet on the Flow Dynamics of a Fluidic Oscillator: Active Flow Control Actuators

The fluidic oscillator shows very promising outcomes as an actuator in active flow control applications as it features several important characteristics that include no moving parts, self-excitation, rigidity, and reliability. The fluidic oscillator can be used in many diverse applications including active combustion control in jet engines and flow separation control on diverse aerodynamic profiles. This book deals with a small-scale double feedback fluidic oscillator, where the design was adopted from a previous study to meet working as a pilot oscillator inside swirl stabilized burners. The present work investigates computationally the influence of the exit configurations on the flow dynamics of the fluidic oscillator.
