Laser and X-ray Diagnostics for a Physics-based Understanding of Aero-thermal Flows
Flows in high-speed boundary layers and modern propulsion devices are characterized by widely varying levels of turbulence, chemical reactions, temperatures, and pressures. These flows often exist within optically complex environments, including shock-wave interactions, intense near-wall gradients, ablative surfaces, plasmas, reactions of energetic materials, and other multi-phase phenomena. Understanding and predicting the performance of next-generation aero-propulsion devices and novel materials, therefore, requires advanced diagnostics that can resolve a broad range of spatiotemporal scales, interrogate multiple phases, and extract quantitative information about velocity and state variables within such challenging conditions. This talk discusses key innovations in ultrafast and ultrahigh-speed laser and X-ray diagnostic techniques that allow quantitative measurements of temperature, pressure, species, and liquid-solid-vapor mass distributions in highly dynamic environments. Recent efforts have focused on (i) achieving orders of magnitude improvements in spatio-temporal resolution and sensitivity of these techniques and (ii) the application of simultaneous multiparameter measurements in flows of practical interest. Finally, prospects for further innovations and coupled numerical simulations for the study of highly complex aero-thermal flows are discussed.
Biography: Dr. Terrence Meyer is a Professor of Mechanical Engineering and a Professor of Aeronautics and Astronautics (by courtesy) at Purdue University, where he specializes in the development and application of novel laser and X-ray diagnostics for aero-thermal flows. After earning a PhD at the University of Illinois at Urbana-Champaign in 2001, Dr. Meyer worked as a Research Scientist at the Air Force Research Laboratory in Wright-Patterson AFB, Ohio. He then joined the faculty at Iowa State University in 2006 and Purdue University in 2015. He also served as a Visiting Assistant Professor at the Ecole Centrale Paris in France between 2001-2003 and as a Guest Professor at the Friedrich-Alexander University in Germany between 2010-2020. He has been very active in innovation, service, and outreach activities. He has chaired or co-chaired over a dozen technical symposia, published five book chapters/tutorials, and delivered five short courses on diagnostics for highly dynamic flow phenomena. His honors include the SAOT Young Researcher Award, the NSF Career Award, the AIAA Aerodynamic Measurement Technology Innovation Award, the Spira Award, and six semesters as an Outstanding Engineering Teacher at Purdue University. He is an Associate Fellow of the AIAA, and he is a Fellow of the Combustion Institute, ASME, and Optica, for which he also serves as an Associate Editor.
