Growth of Carbon Particles in Rocket Exhaust

Abstract

The specific approach taken in this work was to study particle formation in a cooling jet of carbon vapor diluted by an inert carrier gas. Vapor was produced by the evaporation of a resistance heated graphite tube. The carbon vapor, mixed with carrier gas, flowed into a light scattering chamber where spectroscopic measurements were used to monitor concentrations of molecular species. Particles were also collected for electron microscopy. An initial reaction leading to particle formation was identified as C2+C3 yields C5 with a gas kinetic rate. Particulates were found to be spherical, of approximately equal diameter and frequently chained in the manner of hydrocarbon soot.
