The friction of sliding wet textured surfaces: the Bruggeman effective medium approach revisited

Abstract: ResearchCite this article: Scaraggi M. 2015 The friction of sliding wet textured surfaces: the Bruggeman effective medium approach revisited. Proc. R. Soc. A 471: 20140739. http://dx.The mean field fluid dynamics and the friction occurring in the wet sliding contact between inhomogeneous surfaces, characterized by a deterministically repeated pattern of microdefects, are modelled within the Bruggeman effective medium theory. By comparing with the results of an accurate numerical homogenization of the flow equa… Show more

“…random roughness can be calculated using the critical junction theory or the Bruggeman effective medium theory as described in detail elsewhere [21][22][23][24][25][26][27][28][29]. In the critical junction theory it is assumed that all the pressure drop in the fluid occurs at the most narrow constrictions along the biggest open (percolating) flow channels.…”

“…There are several different (but related) effective medium theories, e.g. the coherent potential approximation or the Bruggeman effective medium approximation [15][16][17][23][24][25][26][27]. In earlier publications we have shown how the leakage of seals can be accurately described using the Bruggeman effective medium theory for systems with random but isotropic surface roughness [12].…”
