Keywords: Active Flow Control, Coanda Surface, CFD, Sweeping Jet Actuator


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.

Kursat Kara

Kursat KARA is an Assistant Professor of Aerospace Engineering at the Khalifa University, Abu Dhabi, UAE. He received his BS and MS degrees from Istanbul Technical University and PhD degree from Old Dominion University, Norfolk, VA, USA in 2008. His doctoral dissertation was on hypersonic boundary layer receptivity to acoustic disturbances over cones. Following graduation he was a research engineer at New England Analytics LLC, Shelton, CT consulting company to Sikorsky Aircraft Corp. He then joined to the Aerospace Engineering Department at Penn State as a post-doctoral research associate and worked with Prof. Philip J. Morris. In 2010, he joined Khalifa University. Dr. Kara’s research interests include computational aerodynamics / fluid dynamics, hypersonic boundary-layer transition (DNS), supersonic hot jet simulations for aeroacoustics (DES), high order accurate schemes (WENO, DRP), active flow control wind turbine blades (with Dr. Sankar from Georgia Tech), wind energy and spray cooling of electronics. His research has been funded by the NASA Langley Research Center, the U.S. Navy Naval Air Systems Command (NAVAIR) and Khalifa University. Dr. Kara is a Senior Member of AIAA, Member of AIAA Applied Aerodynamics Technical Committee, and the technical chair of 34th Applied Aerodynamics Conference (June 2016, Washington DC, USA).
