Abstract
A modified Wolfhard-Parker slot burner was designed and constructed for the purpose of producing stable, planar diffusion flame sheets. The flow field above the burner was characterized by flow visualization, Laser Doppler velocity (LDV) and thermocouple temperature measurements. This characterization indicated that a 10 cm high, stable, nearly laminar diffusion flame sheet was produced on the burner. Laser-induced fluorescence (LIF) measurements of the temperature of OH radicals in the flame sheet were performed. Two fluorescence detection schemes were used. The LIF temperature measurement results in the flame sheet were compared to LIF temperature measurements made previously in a Bunsen burner flame. The results in this study supported the notion that the use of a narrowband detection scheme can result in a spectral bias of the fluorescence signals. The advantages of using stable, planar diffusion flames as produced by the Wolfhard-Parker burner for further OH LIF measurements were demonstrated through the LIF results of this study. Fundamental differences between the flames produced by different burners affects the accuracy of spectroscopic diagnostic results.
