Contact angle influence on the pull-in voltage of microswitches in the presence of capillary and quantum vacuum effects [PDF]
, 2007 Capillary condensation between the electrodes of microswitches influences the effective pull-in voltage in a manner that depends on the contact angle of the capillary meniscus and the presence of plate surface roughness.

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 ...

The contact angle in inviscid fluid mechanics [PDF]
, 2004 We show that in general, the specification of a contact angle condition at the contact line in inviscid fluid motions is incompatible with the classical field equations and boundary conditions generally applicable to them.

Experimental consideration for contact angle and force acting on bubble under nucleate pool boiling
Nuclear Engineering and Technology, 2023 Pool boiling experiments are performed within an isolated bubble regime at inclination angles of 0° and 45°. When a bubble grows and departs from the heating surface, the pressure, buoyancy, and surface tension force play important roles.

A new model for contact angle hysteresis
Networks and Heterogeneous Media, 2007 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 ...

Fluids, 2021 The measurement of the apparent contact angle on structured surfaces is much more difficult to obtain than on smooth surfaces because the pinning of liquid to the roughness has a tremendous influence on the three phase contact line. The results presented

A noise-resistant ADSA-PH algorithm for superhydrophobic surface’s static contact angle evaluation
AIP Advances, 2017 The blur around the contact points significantly decreases the evaluated static contact angle for superhydrophobic surface which is clearly presented in the paper. To improve the accuracy in the evaluated static contact angle for superhydrophobic surface,
