Effortless preparation of superhydrophobic surfaces mimicking the wetting characteristics of lotus leaf is of interest to several works. Spray coating methods using hydrophobic solutions are often adopted to realize such superhydrophobic surfaces. The present study investigates the dynamic behavior of impacting water drops on an aluminum surface coated with commercially available hydrophobic solution...
We conduct a numerical study to investigate the effect of surfactants on the drop formation process in a co-flowing system using a hybrid volume-of-fluid (VOF) method combined with a front-tracking scheme. The drop and bulk phases are treated as incompressible Newtonian fluids, and the surfactants are modeled using a Langmuir adsorption framework. We consider the effect of soluble surfactants in the...
