Colliding-Jet Fluidic Actuators for Active Flow Control, Phase I

Completed Technology Project

Project Introduction

We propose a novel method of producing sweeping jets using a simplified geometry that is very short in stream-wise length and no feedback channels inside. This rugged design is expected to be more efficient, occupies about 50% less space (and hence less weight) when scaled-up compared to the existing feedback-oscillator-based actuators and hence offers advantages in developing a flow control system that can be more suitable for integration into aerodynamic configurations. In Phase I, we propose to optimize the geometry for stable operation with high momentum output, and minimum streamwise length. Scaling studies will be conducted for the best design to obtain scaling laws for scale-up to full-scale. We will also develop concepts of actuator arrays with integrated plenum chamber. In Phase II, we plan to demonstrate the use of these actuators for flow control in a blended wing or on a thin airfoil flap. More »
