Soot Particles Size and Concentration Determination from a Kerosene/ Gaseous Oxygen Rocket Plume

摘要

An experimental investigation was conducted to measure soot properties and concentration, and infrared signature of the plume of a kerosene/ gaseous oxygen rocket motor. Multiple-wavelength measurements were used to obtain soot parameters. It was found that the multiple-wavelength technique appeared to work well for obtaining soot properties and concentration. The results implied that the soot particulate was very porous for the most fuel-rich conditions and became more compact as the 0/F ratio increased.
