   "Natural surfaces have micro and nano structures that affect the splashing behavior of water droplets falling on them. Synthetic surfaces mimicking this natural phenomenon have been previously reported. The objective of our current work is to design such surfaces and fine tune the fluid splashing behavior using three-dimensional(3D) simulation tools. We have designed and simulated splashing behavior on geometrically patterned micro scale surfaces using the Volume of Fluid(VoF) method. Surfaces with micro scale pillars of different heights, geometrical shapes, layouts as well as tip designs were simulated with the goal of minimizing fluid splash. We found that certain pillar models produce less splashes than others. We have further optimized array structures for fluid splashing diameter and velocity. Behavior at different falling angles and fluid types are also investigated in multi-pillar models. The results indicate that a non-uniform structured surface decreases the speed and energy of the falling droplet. We have reported here three finalized designed models that are 35%, 63.5% and 69% effective in reducing splash compared to a flat surface model."

Projects

1. Design, Fabrication and Performance Analysis of 3D anti-splashing surface

   Aim: We're currently crafting a cutting-edge surface as a key component of our ongoing research endeavor. This innovative surface is meticulously designed to minimize liquid splashes. Leveraging advanced fluid physics simulations, particularly with the support of Ansys Fluent, we've fine-tuned multiple parameters to perfection. Our exploration has led us to utilize top-tier materials like SLA-resin and PDMS, ensuring the utmost effectiveness and durability of the structure.
