Simultaneous measurements of burning velocity and temperature distribution of combustion using UV laser Rayleigh scattering

Planar temperature images using laser Rayleigh scattering have been obtained to determine the spatial distribution of in a constant volume combustion chamber. Burning velocities were also measured from pressures and calculated flame surface area images. A high power KrF excimer was used as light source gain ICCD camera obtain Methane/air premixed at different equivalence ratios initial tested. Since thermodynamics are well known, chamber can be reference device for diagnostics temperatures combustion. With technique, burning velocity simultaneously single-shot light. An additional experiment is described which yields cross sections wavelength 248 nm. The experimental results show an excellent agreement with previous data.
