Effects of Ethanol Mixing Ratio on Spray Characteristics of Triplet Impinging Injector
에탄올 혼합비에 따른 3중 충돌형 인젝터의 분무특성
- Published : 2007.12.31
Abstract
Spray characteristics of a unlike triplet injector were investigated experimentally. Spray images and SMD of droplet were measured to evaluate the spray characteristics injected by liquid/gas combinations. G-L-G(Gas-Liquid-Gas), L-G-L(Liquid-Gas-Liquid) type of injector were used by changing the gas and liquid feed lines. The SMD graph shows that the droplet sizes decrease in the out of radial direction at a fixed gas Reynolds number. The SMD value of decreasing tendency shows that the more ethyl alcohol ratio increase, the more SMD value decrease.
