Abstract

The effects of unsteadiness and fuel Lewis number (Le_F) on Burke-Schumann type diffusion flames were studied. Systematic determination of the effect of Le_F on flame temperature and NO_x was experimentally observed in laminar and turbulent flames. Helium and argon diluted methane, propane, and hydrogen diffusion flames in a Burke-Schumann configuration were studied. Varying the dilution level of these two inert gases allowed for Le_F to change over a wide range of values. Vortices generated by a loudspeaker with controlled frequencies and amplitudes were introduced in the fuel stream to systematically determine the combined effect of unsteadiness and Le_F) in diffusion flames. Implications of NO_x and soot emission will be discussed as a result of dilution and varying Lewis number.
