摘要

The evaporation of droplet on a substrate is a hot topic. Considering the droplet shape as a spherical cap, the equations about the droplet evaporation rate of the constant contact angle stage, the constant contact diameter stage and the transitional stage are theoretically analyzed and verified by experiments. The results show that three stages are shown in the evaporation process, and the evaporation rates in these three stages coincident with the theoretical conclusion. In the constant contact angle stage, the evaporation rate is proportional to the square of base radius. While in the constant contact diameter stage, the evaporation rate is proportional to the cube of base radius. The evaporation rate in the transitional stage approximates to that of the constant contact angle stage.
