Experimental characterization of water droplet dynamics on micro/nanostructured additively manufactured metal alloys

Abstract

The exponential growth of global industrial output has resulted in a pressing need for energy-efficient devices. Superhydrophobic surfaces possess desirable properties, such as self - cleaning and anti -adhesion, which is highly advantageous in certain industrial settings. Conversely, superhydrophilic surfaces can enhance the performance of liquid cooling systems by promoting better wicking and spreading of the working fluid during phase change. To explore these effects, this project investigates the dynamics of water droplet impingement, spreading, and evaporation across these enhanced surfaces.

Droplet impingement test was performed to characterize the different types of superhydrophobic surfaces. Wicking and evaporation experiment was conducted to characterize superhydrophilic surfaces.
