Multiphase Detonation Physics for Next-Generation Propulsion
Project Description
Join and help lead a dynamic team investigating the fundamental physics of multiphase detonation, with a focus on discovering and describing how particles dispersed within reactive gases contribute to detonation performance. This research will leverage and advance a unique detonation facility in which carbon soot and other particles are introduced into reactive gas mixtures. Detonation time histories will be quantified using a suite of advanced diagnostics, including schlieren imaging, laser-induced incandescence, laser-induced fluorescence, coherent Raman scattering, and other cutting-edge methods that the postdoctoral researcher will help develop. Measurement results will be integrated to deepen fundamental understanding and support the development of predictive models for detonation performance. The postdoctoral researcher will incorporate these developments to experimentally demonstrate improved performance in advanced propulsion concepts, including rotating detonation engines (RDEs), within the nation’s largest academic propulsion test facility. These interdisciplinary efforts will strengthen the researcher’s expertise in fundamental combustion, advanced experimental diagnostics, and the leadership of large-scale ground test facilities, contributing to the advancement of defense propulsion missions. Successful research outcomes will establish national recognition in this rapidly evolving field and provide the skillset to become a next-generation thought leader.
