RECENT DEVELOPMENTS IN DROPLET INTERACTION WITH MESH SURFACES

The impact of droplets on porous and mesh surfaces has attracted significant attention due to their relevance in diverse applications, including spray coating, water oil separation, fog collection, inkjet printing, liquid atomization, and spray cooling. This study presents recent advancements in understanding the dynamics of drop impact on porous surfaces, identifying key regimes such as deposition, partial imbibition, and penetration. It investigates the effects of liquid properties, impact conditions, and mesh characteristics on these phenomena. The findings demonstrate the role of impact velocity in governing penetration and splashing behavior, as well as the influence of pore size and geometry on droplet dynamics. Liquid viscosity is shown to regulate spreading, elongation, and penetration thresholds, while surface wettability dictates dispersion patterns and rebound behavior. Numerical modeling has augmented experimental studies, enabling the exploration of scenarios that are difficult to replicate experimentally. This review advances the comprehensive understanding of droplet impact dynamics, facilitating the development of future research and applications in industrial processes.
