Abstract

The potential of several flame observables to yield a simplified measurement of the scalar dissipation rate was studied. The possibility of a simplified measurement stems from the realization that the related gradient of the mixture fraction scales as the inverse of an appropriately defined thickness of the mixing layer. The utilization of several flame observables for the measurement of the thickness, in a flat, nitrogen diluted, counterflow, methane/oxygen diffusion flame, the scalar dissipation rate was first measured directly using line Raman imaging of major species and a N₂-molecule based definition of the mixture fraction. Laser-induced fluorescence measurements of the hydroxyl radical and formaldehyde as well as Raman measurements of CO were performed across the flamelet.
