Advanced Combustion via Microgravity Experiments / Coflow Laminar Diffusion Flame

In order to provide the experimental data needed to allow rigorous testing of computational models at the extremes of the fuel dilution spectrum, we have the following objectives: A) Characterize the behavior of weak coflow diffusion flames of methane and ethylene, as a function of velocity and fuel dilution, through measurement of flame shape, lift-off heights, temperatures and extinction limits. B) Characterize the sooting tendencies of diffusion flames with long residence times, as a function of velocity and fuel dilution, through measurement of flame shape, gas temperatures in the soot-free portion of the flame, soot luminosity, soot temperatures, and soot volume fractions.
