Computational And Experimental Study of Spanwise Synthetic Jet Flow Control
Howard Ho, Adnan Machado, Pierre Sullivan
This study investigates the reattachment of flow on a stalled NACA 0025 airfoil with an array of circular synthetic jet actuators. Experimental flow visualizations are used to asse…
Characterizing 3D Reattached Flow on an Airfoil with Finite-Span Synthetic Jets
Adnan Machado, Pierre E. Sullivan
This paper synthesizes prior studies to develop a comprehensive three-dimensional description of reattached flow over an airfoil controlled by finite-span SJA arrays. When applied…
Role of Duty Cycle in Burst-Modulated Synthetic Jet Flow Control
Adnan Machado, Ali Shirinzad, Kecheng Xu +1
The effect of duty cycle (DC) and blowing ratio on synthetic jet flow control over a stalled NACA 0025 airfoil at Re_c=10^5 was investigated experimentally. A finite-span microblow…
Spanwise Control Authority of Synthetic Jets on a Stalled Airfoil
Adnan Machado, Kecheng Xu, Pierre E. Sullivan
This study investigates the aerodynamic effects of low- and high-frequency synthetic jet control strategies on a National Advisory Committee for Aeronautics (NACA) 0025 airfoil. Vi…
On the Role of the Wall Curvature in the Development of Flows Reattached over an Airfoil through Unsteady Blowing
Ali Shirinzad, Kecheng Xu, Pierre Edward Sullivan
An array of twelve circular-orifice synthetic jet actuators (SJAs) was used to provide the unsteady forcing required for flow separation control over a National Advisory Committee…
Improving 3D Synthetic Jet Modeling in a Crossflow
Howard Ho, Ebenezer Essel, Pierre Sullivan
Three different circular synthetic jet modeling inlet conditions are studied for a turbulent crossflow. The study examines the differences when modeling the whole SJA, neck-only or…
Visualizing Three-Dimensional Effects of Synthetic Jet Flow Control
Adnan Machado, Kecheng Xu, Pierre E. Sullivan
This study investigates the three-dimensionality of synthetic jet flow control over a NACA 0025 profile wing using horizontal and vertical smoke wire visualization. The stalled flo…
