Superhydrophobictextile material having self-cleaning function was developed by employing carbon nanotubes (CNTs) and water-repellent agents.Hydrophobic fabrics were prepared on 100% polyester woven fabrics withvarious yarn diameters and yarn types.

Inertial coalescence of droplets on a partially wetting substrate [PDF]
We consider the growth rate of the height of the connecting bridge in rapid surface-tension-driven coalescence of two identical droplets attached on a partially wetting substrate.

Contact Angle Hysteresis on Superhydrophobic Stripes
We study experimentally and discuss quantitatively the contact angle hysteresis on striped superhydrophobic surfaces as a function of a solid fraction, $\phi_S$.

Effect of contact angle and helix angle on slide-roll ratio under the uniform motion state of BSM
To study the effect of contact and helix angles on slide-roll ratio at the ball contact point under the uniform motion state of ball screw mechanism (BSM), a slide- roll ratio model was derived in the literature [9] were used in this paper.

A comparison of slip, disjoining pressure, and interface formation models for contact line motion through asymptotic analysis of thin two-dimensional droplet spreading [PDF]
The motion of a contact line is examined, and comparisons drawn, for a variety of models proposed in the literature. Pressure and stress behaviours at the contact line are examined in the prototype system of quasistatic spreading of a thin two ...

Determination of contact angle hysteresis of water microdroplets evaporating on hydrolyzed PET foils [PDF]
Moderately hydrophobic surfaces of PET foils were gradually hydrophilized by their immersion in NaOH solutions of increasing concentration. Then, the contact angle and geometric factors of microliter water drops, deposited on these polymer surfaces, were

A Kinematic Evolution Equation for the Dynamic Contact Angle and some Consequences
We investigate the moving contact line problem for two-phase incompressible flows with a kinematic approach. The key idea is to derive an evolution equation for the contact angle in terms of the transporting velocity field.

Asymptotic expansions of the contact angle in nonlocal capillarity problems [PDF]
We consider a family of nonlocal capillarity models, where surface tension is modeled by exploiting the family of fractional interaction kernels $|z|^{-n-s}$, with $s\in(0,1)$ and $n$ the dimension of the ambient space.

The dynamic contact angle, the angle between the surfaces of the liquid and the solid at a moving contact line, is one of the primary conditions for the dynamics of the liquid surface confined by solid wall.

We discuss an evaporation-induced wetting transition on superhydrophobic stripes, and show that depending on the elastic energy of the deformed contact line, which determines the value of an instantaneous effective contact angle, two different scenarios ...
