Abstract

Proper control of the droplet impact mechanism is very crucial in enhancing efficient use of resources in a variety of industrial practices such as spray cooling, anti-icing systems, and surface coating processes. To determine how droplet impingement occurred over time, the current study focuses on the investigation of such a process on micro- and micro/nanotextured and lubricant-infused surfaces (LIS). The visualization of impact events at different Weber numbers (We = 2~200) was carried out by means of high-speed imaging. Microelectromechanical systems (MEMS) fabrication techniques were applied to realize precise surface engineering. The findings show a significant increase in the droplet deposition and the accompanying inhibition of splashing, which directly provides a benefit on resources utilization and process stability. When connecting results to SDG 9.4 that suggests upgrading the existing industrial infrastructure by aiming to achieve the high degree of resource-use efficiency, the given study emphasizes that the most breakthrough surface engineering mechanisms hold great potential to transform sustainable industrial processes.
