Abstract

Spherically-symmetric droplet combustion experiments were performed in an effort to better understand the mechanism leading to sootshell formation. The experiments were performed at the NASA Glenn Research Center (GRC) 2.2 s droptower in Cleveland, OH. Rapid insertion of a blunt plunger was used to remove the symmetric sootshell that formed during the period of quasi-steady burning. This allowed for the observation of sootshell re-formation. Soot particles were formed near the flame front and migrated towards the droplet to ultimately reside at the sootshell location. These experiments helped to bring about a better understanding of soot transport in microgravity droplet combustion.
