On the Dynamic Contact Angle in Capillary Flows [PDF]
Journal of Chemical and Petroleum Engineering, 2021 The displacement of the contact line (CL) between two arbitrary immiscible flowing fluids was modeled. The present model is valid for a wide range of viscosity ratios of the phases. This is while the previously developed models reported in the literature

Contact-Angle Hysteresis and Contact-Line Friction on Slippery Liquid-like Surfaces
Langmuir, 2020 Contact-line pinning and dynamic friction are fundamental forces that oppose the motion of droplets on solid surfaces. Everyday experience suggests that if a solid surface offers low contact-line pinning, it will also impart a relatively low dynamic ...

The Possibility of Changing the Wettability of Material Surface by Adjusting Gravity
Research, 2020 The contact angle, as a vital measured parameter of wettability of material surface, has long been in dispute whether it is affected by gravity. Herein, we measured the advancing and receding contact angles on extremely low contact angle hysteresis ...
