Enhancing Jet Breakup via High-Frequency Ultrasound
Abstract
Rapidly adjustable and reliable fuel injection in harsh conditions is key in modern military aircraft engines. To advance injector technology to support missions with the necessary fuel efficiency, stealth, and noise reduction needed today and necessary in the future, we explore and reduce the major risks in introducing high temperature tolerant, 10 MHz-order ultrasound devices to enhance droplet formation in fuel ejected from cross-flow nozzles into high-speed combusting flows. The mechanisms we propose to use are only now being elucidated with novel analysis by our team, composed of a leading aircraft engine manufacturer, a leading aircraft engine combustion research team, and a leading research team on nonlinear acoustics in complex flows. These efforts eliminate lengthy computations and promise simple design tools for effective integration of this technology into aircraft engines using recent developments in fuel spray control by the ONR-supported MURI team
