The measurements of species time histories using lase r absorption technique provide a meaningful database to tune the reactivit y of detailed kinetics models\, as it permits to identify key elementary r eactions. Tremendous efforts to increase model fidelity led to excellent m echanisms’ agreement with experiments and improved reliability in predic ting fuel combustion. 1) Our work on pentene isomers is now considered as the most reliable model for these hydrocarbons and can be used by the indu stry to design better engines. 2) The flammability from the EV was address ed through incremental studies\, and\, as far as we know\, there is no oth er model available in the literature able to predict the combustion proper ties of a battery electrolyte with a validated fire suppressant. 3) A newl y developed HCl laser diagnostic permitted to obtain the first HCl quantif ication of a propellant surrogate extensively used in propulsion\, represe nting unique target data to develop models that are much required.\n\nBiog raphy\nDr. Grégoire is a postdoctoral researcher in the Department of Mec hanical Engineering at Texas A&\;M University within the Turbomachinery Laboratory. She received her Ph.D. with Prof. Petersen in the same group and her research entails the experimental study on combustion processes wh ile developing detailed chemical kinetics model that are crucial for susta inable transportation energy and safety of next-generation lithium-ion bat teries. Dr. Grégoire is an expert in laser absorption spectroscopy and op tical diagnostics\, specializing in their application in shock tube experi ments to investigate reaction chemistry at conditions relevant to advanced combustion systems. The development of a HCl laser absorption diagnostic to investigate the combustion kinetics of solid rocket propellants was her final thesis’ project. Her Ph.D. work has led to the publication of 22 peer-reviewed scientific articles\, and she is firmly determined to contin ue contributing to the chemical kinetics community.\n\nMAE Faculty Host: R yan Houim CATEGORIES:Seminars LOCATION:MAE-A Room 303\, 939 Sweetwater Drive\, Gainesville\, FL\, 32611\, United States GEO:29.643814;-82.34865 X-APPLE-STRUCTURED-LOCATION;VALUE=URI;X-ADDRESS=939 Sweetwater Drive\, Gain esville\, FL\, 32611\, United States;X-APPLE-RADIUS=100;X-TITLE=MAE-A Room 303:geo:29.643814,-82.34865 END:VEVENT BEGIN:VTIMEZONE TZID:America/New_York X-LIC-LOCATION:America/New_York BEGIN:STANDARD DTSTART:20241103T010000 TZOFFSETFROM:-0400 TZOFFSETTO:-0500 TZNAME:EST END:STANDARD END:VTIMEZONE END:VCALENDAR
