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 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.

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.

Universal contact-line dynamics at the nanoscale
, 2015 The relaxation dynamics of the contact angle between a viscous liquid and a smooth substrate is studied at the nanoscale. Through atomic force microscopy measurements of polystyrene nanostripes we monitor simultaneously the temporal evolution of the ...

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

Research on the elastic–plastic external contact mechanical properties of cylinder
Science Progress, 2020 Based on Hertz contact theory, an elastic-plastic contact mechanics model of outer cylinder under different contact angles of axis is proposed. The relationship among contact angle, load and contact deformation, contact stiffness and contact area is ...
