COANDA SURFACE EFFECT ON THE SWEEPING JET ACTUATOR
Keywords:
Active Flow Control, Coanda Surface, CFD, Sweeping Jet ActuatorAbstract
A sweeping jet (SWJ) actuator emits a continuous but spatially oscillating jet when pressurized with a fluid. In this study, unsteady flow fields generated by a SWJ actuator are investigated using two-dimensional, unsteady, Reynolds-Averaged Navier Stokes (2D-URANS) simulations with Ansys v17 Fluent software over a nine different Coanda Surfaces. The effect of varying Coanda surface as well as mass flow rate on the jet velocity profile is presented. Additionally, the Static and Total Pressure are analyzed in order to determine the pressure drop of each Coanda Surface. Fast Fourier Transform (FFT) of the jet is studied for the velocity magnitude in a characteristic point of the SWJ with different Coanda Surfaces.
