Numerical study of the wetting dynamics of droplet on laser textured surfaces: Beyond classical Wenzel and Cassie-Baxter model

The classical wetting models, such as the Wenzel and Cassie-Baxter have been extensively used to quantify wettability of laser-textured surfaces. However, these models do not provide any description corresponding droplet dynamics. In this work, we propose a detailed continuum-level modelling study dynamics water on Ti-6Al-4V alloy. calculations are performed for flat surfaces with various reliefs. calculated evolutions spreading parameter surfaces, triangular reliefs one two different periods heights only explanations several experimental results but also underline perspectives using complex efficient control. Thus, simulations shown be useful in relief design laser texturing wide range applications, example, treatment artificial implants prostheses.
