摘要

Soot nanoparticles produced during combustion exhibit diverse nanostructures, which are affected by different combustion parameters such as flame stoichiometry and temperature. This work focuses on characterizing RP-3 jet flame properties and exploring the intricate relationship between the effect of temperature and carbon formation. The observed flame length displayed a notable increase in proportion to the equivalence ratio’s growth. The flame color underwent a great transformation, evolving from pale blue in fuel-lean conditions to bright green at stoichiometric levels, and to brilliant yellow under fuel-rich conditions. Through systematic sampling and thorough observation of soot morphology at different flame heights, there is a clear correlation between the height of the flame and the acceleration of carbon agglomerate growth. Furthermore, an insightful observation is presented wherein the rise in flame height leads to a gradual reduction in the contribution of surface growth to the overall soot particle size. These findings contribute significantly to the understanding of the complex interplay between combustion conditions and soot nanostructures. The trends in flame characteristics, coupled with insights into soot morphology, provide a foundation for comprehending the underlying mechanisms governing soot formation in RP-3 flames. These results contribute to the understanding of combustion dynamics, offering valuable perspectives for optimizing combustion processes and elucidating the environmental implications of flame-formed soot.
