GeCheng Zha

GeCheng Zha is a Professor in the Department of Mechanical & Aerospace Engineering at the College of Engineering, University of Miami. His research focuses on advanced aerodynamic concepts and flow control technologies, particularly in the area of Co-Flow Jet (CFJ) systems.

Dr. Zha's research interests center on aerodynamics and flow control, with a particular emphasis on Co-Flow Jet technology. His work explores how CFJ can be applied to various aerospace challenges including:

• High-lift coefficient systems for aircraft and Martian flight
• Flow separation control in extreme adverse pressure gradients
• Energy-efficient flow control mechanisms
• Serpentine duct flow management
• Wind energy applications using cylinder wind sails

Dr. Zha's recent publications demonstrate a consistent focus on Co-Flow Jet technology applications across multiple domains. His work shows how CFJ can achieve ultra-high lift coefficients (up to 25.13 in some configurations), eliminate flow distortion in serpentine inlets, and improve control surface effectiveness with minimal energy expenditure. His research spans both theoretical computational fluid dynamics studies and practical applications for aerospace systems, with particular attention to energy efficiency metrics. The work has implications for terrestrial aircraft design, Martian exploration vehicles, and wind energy systems.

Dr. Zha leads research efforts in advanced aerodynamics and flow control at the University of Miami. His computational work utilizes high-fidelity simulations including RANS, IDDES, and other advanced CFD techniques to analyze complex flow phenomena. He has secured research funding for projects related to active flow control and aerodynamic efficiency improvement.
