水滴是如何蒸发的?

How do drops evaporate?

Nebojsa Murisic, Lou Kondic

摘要:

我们考虑纯液滴在导热衬底上的蒸发。两个蒸发模型被认为是:一个集中在液相在确定蒸发通量,和其他一个中心的气体/蒸汽相。一个单一的控制方程的滴厚度的演变,包括这两种模式,开发。实验用于估计相关参数。我们展示了如何推导出的控制方程可以用来预测蒸发模型是适当的实验条件下考虑。

英文摘要:

We consider evaporation of pure liquid drops on a thermally conductive substrate. Two evaporative models are considered: one that concentrates on the liquid phase in determining evaporative flux, and the other one that centers on the gas/vapor phase. A single governing equation for the evolution of drop thickness, including both models, is developed. Experiments are used to estimate relevant parameters. We show how the derived governing equation can be used to predict which evaporation model is appropriate under considered experimental conditions.
