As rotating detonation engines continue to be researched for their commercialization, emerging evidence suggests that THFCI can evolve into detonation under certain conditions. The amplification of THFCI is often described as a complex linear process involving the coupling between pressure oscillations and the heat release process. However, this linear assumption breaks down when the nonlinear effects, such as the formation of a shock wave, dominate as the pressure oscillation reaches a stable, saturated level. This research aims to develop and experimentally test the optimal conditions to achieve detonation from THFCI with the assistance of Plasma Actuation.\u003Cbr\u003E\u003Cbr\u003EDate and time: 2026-04-20, 1:00 PM\u003Cbr\u003E\u003Cbr\u003ELocation: BTZ 107 Conference Room\u003Cbr\u003E\u003Cbr\u003ECommittee:\u003Cbr\u003EDr. Wenting Sun (advisor), School of Aerospace Engineering\u003Cbr\u003EDr. Benjamin Emerson, School of Aerospace Engineering\u003Cbr\u003EDr. Oleksandr Bibik, School of Aerospace Engineering\u003Cbr\u003EDr. Rachid Darbali-Zamora, Sandia National Laboratories\u003Cbr\u003E,\u0026nbsp;\u003Cbr\u003E,\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EPlasma-Assisted Smart Injector Control of Tangential High-Frequency Combustion Instabilities for Enhanced Instability-to-Detonation Transition\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Plasma-Assisted Smart Injector Control of Tangential High-Frequency Combustion Instabilities for Enhanced Instability-to-Detonation Transition "}],"uid":"27707","created_gmt":"2026-04-13 18:22:10","changed_gmt":"2026-04-13 18:22:10","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-04-20T13:00:00-04:00","event_time_end":"2026-04-20T15:00:00-04:00","event_time_end_last":"2026-04-20T15:00:00-04:00","gmt_time_start":"2026-04-20 17:00:00","gmt_time_end":"2026-04-20 19:00:00","gmt_time_end_last":"2026-04-20 19:00:00","rrule":null,"timezone":"America\/New_York"},"location":"BTZ 107 Conference Room","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"111531","name":"ms defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
