Studies on the Application of Treated Heavy Oils in Ultrasonics for Farm Engine (III)

Relations between Effect of Treated Heavy Oils in Ultrasonics and Atomization

Abstract

The heavy liquid fuel droplets were injected into ethyl cellulose solution in n-propyl alcohol and photo micrographs of them were taken. When heavy oil was treated by ultrasonics, the effect of atomization, was as follows.
1) Sauter's mean diameter of treated heavy oil in ultrasonics was smaller than untreated one.
2) The maximum diameter showed a similar tendency to Sauter's mean diameter, and the relation between the former and the latter is shown in the following equation.
d_max≅2-2.5_d
3) The phenomenon of atomization concerning treated heavy oil depends on colloidal nature, and lower diameter depends on sludge seperation.
4) The distribution curves of sprays of treated and untreated heavy oil are shown in the following equation.
Treated B heavy oil (LS)
……f=38X^0.5exp(-0.0316X)
Untreated B heavy oil (LS)
……f=7.5X^0.25exp(-0.0237X)
Treated LSB heavy oil
……f=35X^0.5exp(-0.0341X)
Untreated LSB heavy oil
……f=50X^0.5exp(-0.0265X)
