Contact-Angle Hysteresis and Contact-Line Friction on Slippery Liquid-like Surfaces. [PDF]
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 ...

Lattice Boltzmann Modeling of Drying of Porous Media Considering Contact Angle Hysteresis. [PDF]
Transp Porous Media, 2021 Drying of porous media is governed by a combination of evaporation and movement of the liquid phase within the porous structure. Contact angle hysteresis induced by surface roughness is shown to influence multi-phase flows, such as contact line motion of

Measuring Surface Tensions of Soft Solids with Huge Contact-Angle Hysteresis [PDF]
Physical Review X, 2021 The equilibrium contact angle of a droplet resting on a solid substrate can reveal essential properties of the solid’s surface. However, when the motion of a droplet on a surface shows significant hysteresis, it is generally accepted that the solid’s ...

Effect of contact angle hysteresis on measuring matric suction in unsaturated sandy soil [PDF]
Geomatics, Natural Hazards & Risk, 2023 The contact angle plays an important role in matric suction of unsaturated soils, but few studies consider the effect of contact angle hysteresis on matric suction. In this paper, taking sandy soil as an example, the influence of contact angle hysteresis

Contact Angle Hysteresis on Superhydrophobic Stripes [PDF]
The Journal of Chemical Physics, 2014 We study experimentally and discuss quantitatively the contact angle hysteresis on striped superhydrophobic surfaces as a function of a solid fraction, $\phi_S$.

Numerical Study of Drop Motion on a Surface with Wettability Gradient and Contact Angle Hysteresis [PDF]
, 2013 In this work, the motion of a 2-D drop on a surface with given wettability gradient is studied numerically by a hybrid lattice-Boltzmann finite-difference method using the multiple-relaxation-time collision model.
