Dynamics and Structure of Mixed-Mode Flames from Highly Turbulent Premixed to Diffusion
Abstract
The proposed research will reveal the dynamics and structure of turbulent mixed-mode flames which are highly relevant to jet propulsion systems. The Sydney piloted inhomogeneous burner will be employed to stabilize flames over a range of mixture inhomogeneities while the jet in hot co-flow burner will provide a platform to probe highly turbulent premixed flames approaching high-Karlovitz numbers. Joint, high-speed imaging of relevant species such as CH-OH or OH-CH2O will be applied to resolve key structural features of these flames. An assessment of spontaneous Raman measurement for the measurement of temperature at high precision and accuracy is also proposed. The research will provide an improved understanding of mixed-mode combustion and will enrich the data base leading to enhanced computing capabilities for such complex systems.
