Title: High-Speed Compressible Turbulent Reacting Flows From Hypersonics and Energy to Space Rockets and Exploding StarsAbstract: High-speed reacting flows power our everyday life on earth through the heart of many energy generation and propulsion systems such as gas turbines, internal combustion and jet engines. They also power the universe through energy produced in stars, such as in the sun and in the most powerful explosions known in the universe: supernovae explosions.High-speed compressible turbulent reacting flows imposes numerous fundamental challenges driven by significant compressibility effects and strong coupling between exothermic reactions and the turbulent flow. Such combustion regimes are fundamental to the operation of many modern propulsion applications, from gas-turbine/jet engines to scramjets and rotating detonation engines.This presentation will provide an overview of a range of phenomena recently discovered in experimental studies of high-speed, compressible, turbulent reacting flows. The topics include intrinsic instabilities of reacting turbulence, flame-scale turbulence production, the onset of catastrophic transitions, spontaneous runaway mechanism of fast turbulent flames as well as the non-linear compressible combustion regime. Challenges presented by these findings will be discussed based on fundamental understanding of high-speed compressible turbulent reacting flows.About the Speaker: Dr. Ahmed is a professor at the Department of Mechanical and Aerospace Engineering at the University of Central Florida (UCF), a faculty of the Center for Advanced Turbomachinery and Energy Research and the Florida Center for Advanced Aero-Propulsion. Before joining UCF, he was faculty at Old Dominion University. Prior to that, he was a senior aero/thermo engineer at Pratt & Whitney Military Engines working on advance engine programs and technologies (F35 and F22 programs). He also served as faculty at Florida State University. At UCF, Dr. Ahmed leads creative and technologically crucial research in advanced propulsion and energy research focusing on hypersonic and supersonic turbulent reacting flows, deflagrations and detonations, high-speed compressible turbulent flows, and advanced laser optical diagnostics through experimental research and physics-based models with more than $27.9 million in research funding. The research has a broad impact in terms of applications for hypersonics (featured in PNAS), space and jet propulsion, power generation and gas turbine engines, fire safety and extends to supernova science (exploding stars, featured in Science). He has authored over 286 scholarly articles and leads a large research group of 53 students and post-docs.Virtual Location URL: https://ucf.zoom.us/j/97021161245?from=addon

This special lecture is presented by William Patrick Cummings, chair of humanities and cultural studies at the University of South Florida.This is part of the Reaching for the Stars as a Global Citizen: An Intellectual Journey of Asia and the World lecture series. This lecture series provides a rare opportunity for students to learn first-hand from esteemed scholars about one of the most important regions in the world today. Students from UCF's top-ranking schools and programs will develop a more comprehensive understanding on the cultural, political and economic forces that have shaped modern Asia through this Special Lecture Series. Asia has a major role in manufacturing, technology and investment markets. Non-governmental organizations specializing in economic development, healthcare and environmental protection also are active throughout Asia. The goal of this course is to help students become global citizens who look forward to the prospects of cooperation between Americans and Asians in building a better, conflict-free world in the 21st century.
