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

从喷墨打印到微电子喷雾冷却、农药沉积，甚至疾病诊断，蒸发表面上的液滴是许多技术过程的基本原理。表面上的液滴蒸发包括液滴的扩散以及通过界面相变的传质。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。有大量的控制因素影响液滴的蒸发动力学，例如，固体基质的性质、液滴的动态润湿、液滴液体的表面张力和挥发性、大气压力、湿度、两相的温度、液滴形状、这些因素使得固体基质上液滴的蒸发动力学成为一个极其复杂的过程
