This seminar provides insight into the extensive research on the CoFlow Jet (CFJ) active flow control technology. The primary technology integrates injection and suction slots at carefully chosen points on the wing using micro compressors. This technology enables high lift increases in the takeoff and landing and high productivity efficiency at cruise, making it beneficial for the entire flight envelope. To increase system mission efficiency, the CoFlow Jet is demonstrated to have high effectiveness (e.g., increase lift, reduce drag, suppress flow separation), low power requirements, and high-power conversion efficiency. Turbulence diffusion is found to be the major factor that counters the adverse pressure gradient to attach the flow. We will present our comprehensive research that indicates that this is a transformative technology that will enable large increases in range, efficiency, stall limit increase, and separation suppression.
The Speaker: Dr. Gecheng Zha is the Director of the CFD and Aerodynamics Laboratory at the University of Miami. His research focuses on CoFlow Jet active flow control, aircraft design, CFD algorithm and code development, turbulence simulation, wind-tunnel testing, turbomachinery aerodynamics and aeromechanics, fluid–structure interaction, and design optimization. Prior to joining the University of Miami, Dr. Zha worked at GE Aircraft Engines, Pratt & Whitney, and AFRL. He received his Ph.D. from the University of Montréal and was a special student at MIT in Spring 2000. Dr. Zha is a NASA NIAC Fellow, an ASME Fellow, an AIAA Associate Fellow, and is a World Top 2% scientist (ranked by Stanford U./Elsevier).
