Analysis of the impact of RFCC feedstock atomization on physical properties
Thread Content
In analyzing the atomization effect of RFCC, it is believed that physical properties of the liquid to be atomized, such as density, viscosity, and surface tension, have an impact. May I ask, which of these factors is the most significant influencing factor? Some believe it is viscosity, while others think it is surface tension. Which view do you lean towards, and are there any papers to support it?
I think there are many factors that have an impact, but viscosity is likely to be a significant one. When considering the atomization effect, choosing the appropriate feed preheating temperature also takes viscosity into account
Indeed, a higher preheating temperature reduces the viscosity of the crude oil, resulting in better atomization and more thorough contact with the oil agent. Viscosity should have the greatest impact on the atomization effect.
The fragmentation and atomization of oil droplets are closely related to mechanics. Droplets maintain their shape due to surface tension and the cohesive forces between molecules; to change the shape of a liquid, energy must be expended to overcome the surface tension that maintains the droplet’s shape as well as the internal cohesive forces.
