Role of the Dynamic Contact Angle on Splashing.
Physical Review Letters, 2019 In this Letter, we study the splashing behavior of droplets upon impact onto a variety of substrates with different wetting properties, ranging from hydrophilic to superhydrophobic surfaces.

Effect of contact angle and helix angle on slide-roll ratio under the uniform motion state of BSM
MATEC Web of Conferences, 2017 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.

Inertial coalescence of droplets on a partially wetting substrate [PDF]
, 2013 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.

Determination of contact angle hysteresis of water microdroplets evaporating on hydrolyzed PET foils [PDF]
Acta Montanistica Slovaca, 2013 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

Nihon Kikai Gakkai ronbunshu, 2014 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.

A Kinematic Evolution Equation for the Dynamic Contact Angle and some Consequences
, 2019 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]
, 2016 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.

An open microfluidic design for contact angle measurement
Micro and Nano Engineering, 2023 Spontaneous capillary flow in open microchannels is a phenomenon driven by surface energies. The contact angle that the liquid forms with the channel's substrate material and the cross-section of the microchannel decide whether liquid from a connected ...

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