Exploring Viscoplastic Fluid Dynamics in Superhydrophobic Channels 

Join us in this presentation as we delve into the fascinating world of viscoplastic fluid transport through channels with grooved superhydrophobic walls. This presentation examines the effects of groove orientation (longitudinal, transverse, or oblique) on flow behavior using a comprehensive modeling approach and numerical simulations. The study assumes a flat interface between the fluid and trapped air, using the Navier slip law and Bingham model. It covers various parameters, including channel thickness, Bingham number, slip number, and groove orientation angle. The research includes semi-analytical and numerical solutions, highlighting the nonlinear effects in oblique cases and presenting findings on flow mobility and stability.
