Evaporating droplets on a surface is the basic principle in many technological processes starting from inkjet printing to the spray colling of microelectronics, pesticide deposition, and even diagnosis of diseases. Droplet evaporation on a surface is comprised of spreading of the drop alongside mass transfer through interfacial phase change. This is a moving boundary problem that involves the interaction of the liquid-air interface with the solid surface (Three-phase contact line). There are large number of governing factors that influence the evaporation dynamics of droplets, for example, properties of solid substrates, dynamic wetting of droplets, surface tension and volality of the drop liquid, atmospheric pressure, humidity, temperature of both phases, drop shape, etc. These factors make the evaporation dynamics of a droplet on a solid substrate an extremely complex process

在许多技术过程中，从喷墨打印到微电子产品的喷雾冷却、农药沉积，甚至疾病诊断，蒸发表面的液滴都是基本原理。液滴在表面的蒸发是液滴沿界面相变传质的扩散过程。这是一个移动边界问题，涉及液-气界面与固体表面(三相接触线)的相互作用。影响液滴蒸发动力学的因素很多，如固体基质的性质、液滴的动态润湿、液滴的表面张力和体积、大气压力、湿度、两相温度、液滴形状等，这些因素使得液滴在固体基质上的蒸发动力学过程极其复杂。
