摘要：

The evaporation characteristics of fatty acid methyl ester (FAME) mixed with four concentrations of ethanol at 873K and normal atmospheric pressure are studied herein. FAME is used as base oils, and ethanol mass fractions vary from 10%, 20%, 30% to 40%. The experimental results show that the evaporation process of the binary component droplets of FAME-ethanol can be divided into two stages: a fluctuation evaporation stage, and an equilibrium evaporation stage. In these four concentration gradients, micro-explosions occur in the droplet evaporation process. The fluctuation evaporation stage is divided into two stages: a strong fluctuation stage and a weak fluctuation stage. After the micro-explosion, there is still a small amount of ethanol in the droplet. Due to the surface tension of the droplet, a small amount of ethanol cannot make the droplet violently fluctuate. The results show that the earlier the droplet micro-explosion occurs, the more intense it is, and the shorter the lifetime of the droplet is. Different concentrations of ethanol have different improvements in droplet evaporation characteristics. Generally, the higher the ethanol concentration is, the shorter the lifetime of the droplet is. However, increasing the ethanol concentration from 20% to 30% has the most obvious effect on the lifetime of the droplet. © 2021, Shanghai Jiao Tong University and Springer-Verlag GmbH Germany, part of Springer Nature.
