Effect of emulsifier on evaporation and micro-explosion characteristics of methanol-diesel droplets
The micro-explosion of emulsified fuel can promote fuel atomization and mixing,however the key to affect its micro-explosion characteristic is the emulsifier.Emulsified methanol-diesel was prepared by mechanical emulsification and phacoemulsification,to study the effect of emulsifier types and content on the stability and dispersion of micro emulsified methanol-diesel.The results show the dispersion of the micro emulsified methanol-diesel can be improved by using compound emulsifiers and increasing the emulsifier content;The increase of emulsifier content can improve the micro-explosion intensity,delay the initial time of micro-explosion,reduce the droplet life,and reduce the droplet evaporation rate in the stabilization stage;The micro-explosion intensity of methanol emulsifier content ratio of 10∶5 and 10∶8 was increased by 34.3%and 37.6%compared with methanol emulsifier content ratio of 10∶3 respectively.
