Data-Based Modal Decomposition and Reduced Order Model Development for Acoustically Forced Jet Diffusion Flames

Abstract

Data-based modal decomposition will be applied to temporally resolved images from the laminar UCLA EPRL and turbulent Edwards AFRL experiments on coaxial jet diffusion flames. Machine learning tools will be then employed to develop reduced order models with flame lift-off and extinction predictive capabilities. Such an effort will lead to a better understanding of oscillatory combustion. This is relevant for the development of efficient fuel and oxidizer injection systems for liquid rocket engines and air-breathing propulsion systems.
