论小接触角下实现滴状冷凝的可能性

The possibility for realizing dropwise condensation with small contact angle

通过分析液滴在临界态及后续冷凝过程中化学势的变化 ,解释了冷凝器混合冷凝的形成机理 ,并证明了如果降低壁面过冷度以及采用适当措施降低壁面液滴的脱落半径的话 。

In this paper we analyze the variation in the chemical potential of the liquid droplets at the critical state and the condensation that follows, and discuss the mechanism of mixed condensation. It is proved that there is a possibility of realizing dropwise condensation with small contact angle when the super cooling of the condenser surface reduces and the dropoff radius of the droplet on the surface reaches a small value through certain appropriate methods.
