Design of a Wolfhard-Parker burner and setup of the experimental conditions for the study of soot formation in dual-mode diffusion flames

Abstract

The formation of soot emissions in combustion processes poses environmental and efficiency problems which have long concerned scientists and engineers. A Wolfuard-Parker burner was designed and fabricated, to study soot formation in dual-mode diffusion flames, where the products of a lean premixed flame serve as oxidizer to the eventual diffusion flame, simulating a droplet combustion environment in Diesel Engines. Experimental conditions were determined, and the whole burner assembly together . with the laser diagnostic optics were set ready for experiments. An experimental run with a single-mode flame served to confirm the calibration of the optics and demonstrated the flame stability and uniformity. Finally, recommendations for the future work were
