Studying of the Contact Angle Hysteresis on Various Surfaces [PDF]
This paper is devoted to investigation of the contact angle hysteresis on various surfaces. It was carried out by two different methods: measuring the advancing and the receding contact angles and measuring the contact angles at water droplet evaporation

Observation of contact angle hysteresis due to inhomogeneous electric fields [PDF]
Wetting of surfaces can be affected by surface roughness, presence of surface chemical defects, or by electric fields. Here, the authors perform electrowetting experiments on microstriped electrodes and show that the droplet’s static contact angle ...

Effects of Contact Angle on the Hysteresis Effect of Soil-Water Characteristic Curves during Dry-Wet Cycles [PDF]
The hysteresis characteristics of soil-water characteristic curves (SWCCs) under dry-wet cycling conditions are very important for understanding unsaturated soil properties, so it is crucial to propose an accurate and efficient method for predicting the ...

Effect of contact angle hysteresis on thermocapillary droplet actuation [PDF]
Open microfluidic devices based on actuation techniques such as electrowetting, dielectrophoresis, or thermocapillary stresses require controlled motion of small liquid droplets on the surface of glass or silicon substrates.

Apparent contact angle and contact angle hysteresis on liquid infused surfaces. [PDF]
We theoretically investigate the apparent contact angle and contact angle hysteresis of a droplet placed on a liquid infused surface. We show that the apparent contact angle is not uniquely defined by material parameters, but also has a dependence on the

A new model for contact angle hysteresis
We present a model which explains several experimental observations relating contact angle hysteresis with surface roughness. The model is based on the balance between released capillary energy and dissipation associated with motion of the contact line ...

A thermodynamic model of contact angle hysteresis. [PDF]
When a three-phase contact line moves along a solid surface, the contact angle no longer corresponds to the static equilibrium angle but is larger when the liquid is advancing and smaller when the liquid is receding.

A mesoscopic model for microscale hydrodynamics and interfacial phenomena: Slip, films, and contact angle hysteresis [PDF]
We present a model based on the lattice Boltzmann equation that is suitable for the simulation of dynamic wetting. The model is capable of exhibiting fundamental interfacial phenomena such as weak adsorption of fluid on the solid substrate and the ...
