The full calculations for ζ − and ζ + can be found in Supporting Information. Measurements of 5 random areas, shown in Figure 5c , in the inner (attractive) and outer (repulsive) reveal that adhesion in the ζ + regions are double the adhesion in the ζ − regions.
WebThe film theory has been extensively applied to describe the mass transfer in systems in which fluid phases are present. The theory considers that the resistance to mass transfer in a given turbulent fluid phase is present in a thin layer adjacent to the interface that is called a film (Seader et al., 2011).
Web28 de ago. de 2014 · The relative lubricant film thickness λ is the ratio of the minimum lubricant film thickness and the surface roughness of the tooth flanks. ( 3) shows that the reduction of the relative film thickness, increased by growing roughness, leads to micropitting.
