摘要/Abstract

摘要： 为获取运行时间对油水分离动态特性的影响,考虑油水汽三相流、水滴蒸发相变等因素,建立滤油机的油水分离流场的数学物理模型及水滴运动蒸发的相变方程;分析运行时间对油水分离过程中油水汽三相体积分数分布以及轴向脱水率的影响,表明不同运行时间油水汽三相流的动态特性,运行时间显著影响油水分离的脱水效率,为研究滤油机的油水分离机理奠定基础.

关键词: 运行时间, 油水分离, 三相流, 脱水率

Abstract: To study influence of run-time on dynamic characteristics of water/oil separation, a mathematical model is established to describe flow field in vacuum oil purifier. Evaporation of droplet phase transition equations are established, considering effect of three-phase flow of oil/water/vapor and water droplets evaporation phase change. Influences of run-time on oil/water/vapor three-phase volume fraction distribution and axial dehydration rate are analyzed. Dynamic characteristics of oil/water/vapor three-phase flow at different run-time is indicated. Efficiency of dehydration of water/oil separation is enhanced with run-time. It provides a foundation for further research on water/oil separation mechanism in vacuum oil purifier.

Key words: run-time, water/oil separation, three-phase flow, dehydration rate
