RESEARCH AREA 1: MECHANICAL SCIENCES, 1.4 Propulsion and Energetics Investigations of Turbulent Lifted Flame Stabilization in Heated and Vitiated Coflows
Abstract
An improved picture of the impact of hot product recirculation and with a variety of high temperature reactants on flame characteristics is desirable fundamentally. Understanding potential combustion control mechanisms and mechanisms for extinction/ignition issues in practical devices are all served by this research. The intellectual merit of the proposed activity centers on the insight gained into the fundamentals of the reaction zone behavior and associated characteristics such as flame autoignition, re-ignition, stabilization and local extinction. A comprehensive and integrated understanding of these mechanisms and flame phenomena, spanning coflow temps and vitiated air temps to over 1000K, is the major objective of the research. An improved understanding of the mechanisms producing such behavior is important for combustion science, as well as understanding combustor flowfields with autoignition.
