Scaling the Response of Separating Turbulent Boundary Layer to Pulsed Excitation
Speaker: Avraham Seifert, Tel Aviv University, Israel
Series: MAE Departmental Seminars
Location: Bowen Hall Room 222
Date/Time: Friday, April 11, 2014, 3:30 p.m. - 4:30 p.m.
The seminar will start by offering the presenters view of active flow control current status, main challenges and future directions. Then recent experimental results of turbulent separating boundary layer, subjected to pulsed excitation will be presented and discussed. Scaling the response of the excited flow leads to dimensionless optimal magnitude and repetition rates. If time permits comparison criteria for flow control actuators will be presented and discussed.
Dr. Avrahame (Avi) Seifert is a Professor of Mechanical Engineering at Tel Aviv University and also the Head of the Meadow Aerodynamics Laboratory. Prof. Seifert is an expert in low speed Aerodynamics and Active Flow Control. Prof. Seifert received his entire education at Tel Aviv University, before leaving for post-doc at NASA Langley. He is Faculty at Tel Aviv University since 1999. Dr. Seifert published over 50 peer-reviewed Journal papers, has 7 patents (several more pending) and educated more than two dozen graduate students. Prof. Seifert served as the Vice Dean for Research, Engineering and now serves as the Head, School of Mechanical Engineering. His recent research interests focus on energy aspects of flow related systems and the environment. Specifically, Aerodynamic drag reduction of heavy vehicles and enhanced effectiveness of wind turbines, including noise and vibrations. Prof. Seifert is also an expert in developing flow control actuators and few of his patents are in various commercialization stages.
