Spray characteristics of high-pressure swirl injector fueled with alcohol

WANG Xibin, CHEN Wansheng, GAO Jian, JIANG Deming, HUANG Zuohua

Frontiers in Energy 2007, Volume 1, Issue 1,   Pages 105-112 doi: 10.1007/s11708-007-0012-z

Abstract: Under the low back-pressure ambient conditions, the spray behavior exhibited a hollow cone with wideVortexes in the opposite direction existed in the rear part of the spray under low back-pressure ambientconditions while the vortexes formed in the middle part under high back-pressure ambient conditions.The SMD profile of methanol coincided well with that of ethanol under low back-pressure ambient conditions, but displayed a slightly larger value under high back-pressure due to fuel evaporation.
