The design and optimization of next-generation aerospace propulsion and combustion systems requires detailed knowledge of thermodynamic properties such as temperature and density. Turbulence, nonequilibrium, and high-pressure and temperature conditions relevant for modern combustors make for a challenging measurement environment that can exhibit significant spatial variation and fast temporal dynamics. Although conditions are challenging, experimental measurements are critical to improve our understanding of these complex reacting flows and to validate chemical kinetic models used to design new vehicles and propulsion devices. For useful comparison with modeling results, measurements must be sufficiently accurate, include a careful characterization of boundary conditions, and, in the case of unsteady events, simultaneously measure multiple relevant parameters.

This seminar will discuss the development and implementation of hybrid femtosecond/picosecond coherent anti-Stokes Raman scattering (fs/ps CARS) to address these requirements. Advances in spectral simulations for improved accuracy and spatial precision of experimental measurements will be discussed. Novel diagnostic advances and results relevant to plasma-enhanced combustion systems and high-speed vehicles and combustors will be highlighted.

About the speaker...
Dr. Chloe Dedic is an Assistant Professor at the University of Virginia in the Department of Mechanical and Aerospace Engineering. Before starting at UVA in 2018, Dr. Dedic was a visiting researcher with the National Institute of Aerospace (NIA) at NASA Langley Research Center and obtained her PhD in mechanical engineering at Iowa State University in 2017. She was recently awarded a DARPA Young Faculty Award (2020), a NASA Early Career Faculty Award (2020), and an AFOSR Young Investigator Program award (2021).

Dr. Dedic’s research interests are centered around the development and application of advanced laser-based diagnostics and nonlinear spectroscopy techniques to study reacting and nonequilibrium flows with the goal of furthering technologies related to clean and efficient energy utilization and the propulsion and aerodynamics of hypersonic vehicles.
