接触面温度对表面液滴蒸发过程的影响
Effect of Surface Temperature on Droplet Evaporation
摘要
Abstract
In the present study, the effects of the surface temperature of subtract on the evaporation process of water droplets are investigated experimentally. By analyzing the acquired images of the tiny tracer particles inside the water droplets, the effects of surface temperature on the Maragoni flows inside the droplets and the time evolutions of the contact line, contact angle and the volume change of the droplets during the evaporation process were revealed clearly and quantitatively. The measurement results show that as the surface temperature of substrate decreases, the reducing rates of the droplet volume and contact angle become slow. However, when the surface temperature becomes relatively low(e. G., T<5℃). The droplet volume and contact angle are found to increase with time due to the condensation process.关键词
