nowadays cmm machines are widely used in surface measurement and inspection. as inspection results from cmm machine are obtained by the means of measuring surfaces with direct contact, they are more precise than non-contact method (like optical measurement). however, cmm machines give more reliable and accurate results rather than non-contact methods but also these results come with error when ...

We study the dynamics of a spherical colloidal particle pulled along fluid–fluid interface using lattice Boltzmann (LB) simulations. consider an with finite width and include both effects thermodynamics wetting, characterized by contact angle ? between surface interface, in addition to viscosity ratio ? two fluids. characterize applying constant pulling force measure translational rotational as...

Stainless steel 304 (SS304) experiences corrosion when it is exposed to a saline atmosphere, which attains severity due its high surface wettability. Topographical modification of metallic surfaces an effective route reduce wettability and thereby mitigate liquid-mediated corrosion. In this work, topographical stainless flat in the form micropillars was done (pillar width: 100 μm, inter-pillar ...

BACKGROUND The menisci are integral to normal knee function. The purpose of this study was to measure the contact pressures transmitted to the medial tibial plateau under physiological loads as a function of the percentage of the meniscus involved by the radial tear or repair. Our hypotheses were that (1) there is a threshold size of radial tears above which contact mechanics are adversely affe...

The produced liquid water in cathode catalyst layer (CCL) has significant effect on the operation of proton exchange membrane fuel cell (PEMFC). To investigate this effect, the transport of oxygen in CCL in the presence of immiscible liquid water is studied applying a two-dimensional pore scale model. The CCL was reconstructed as an agglomerated system. To explore the wettability effects, diffe...
