摘　　要：固着液滴是指附着于壁面上的液滴,其蒸发行为及传热传质特性是喷雾冷却、喷墨打印等相变传热传质领域的基础问题之一。重点针对固着液滴蒸发过程所涉及的自身形态演变规律、气液固三相耦合传热/传质/流动特性进行了综述。结合毫微尺度固着液滴基本蒸发模式、热质传递形式、气液两相流动特征和界面输运行为,分析了液滴性质、壁面条件、气相环境条件等关键因素对固着液滴蒸发过程的内在作用机制和影响规律,提出了微纳尺度固着液滴(群)热质传递过程与机理的相关研究展望。The sessile droplet is a droplet that adheres to the wall.The evaporation behavior and heat&mass transfer characteristics of sessile droplets are one of the basic problems of phase change heat and mass transfer in many fields,such as spray cooling and inkjet printing.This paper focuses on the sessile droplets evolution during evaporation,and the characteristics of gas-liquid-solid three-phase coupling heat&mass transfer and flow.Combined with the basic evaporation mode,heat&mass transfer form,gas-liquid two-phase flow characteristics and interfacial transport behavior of millimeter and micrometer scales sessile droplets,the mechanism and effect of key factors such as droplet properties,wall conditions and gas phase environment on the droplets evaporation process are analyzed in detail.Based on the current research status,prospects for related research on the process and mechanism of heat&mass transfer in micro-and nano-scale sessile droplets(swarmsa)re presented.
