I show that the Bruggeman effective medium theory and the critical junction theory give nearly the same results for the fluid flow conductivity. This shows that, in most cases, the surface roughness observed at high magnification is irrelevant for fluid flow problems such as the leakage of static seals, and fluid squeeze-out. The effective medium theory predicts that the fluid flow conductivity vanishes at the relative contact area A/A0 = 0.5 independent of the anisotropy. However, the effective medium theory does not solve the elastic contact mechanics problem but is based on a purely geometric argument. Thus, for anisotropic roughness the contact area may percolate at different values of A/A0 depending on the direction. We discuss how this may be taken into account in the effective medium and critical junction theories. 000875241 536__ $$0G:(DE-HGF)POF3-141$$a141 - Controlling Electron Charge-Based Phenomena (POF3-141)$$cPOF3-141$$fPOF III$$x0 000875241 588__ $$aDataset connected to CrossRef 000875241 773__ $$0PERI:(DE-600)2004003-9$$a10.1140/epje/i2020-11951-2$$gVol. 43, no. 5, p. 25$$n5$$p25$$tThe European physical journal / E$$v43$$x1292-8941$$y2020 000875241 8564_ $$uhttps://juser.fz-juelich.de/record/875241/files/Persson2020_Article_InterfacialFluidFlowForSystems.pdf$$yOpenAccess 000875241 8564_ $$uhttps://juser.fz-juelich.de/record/875241/files/Persson2020_Article_InterfacialFluidFlowForSystems.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000875241 8767_ $$92020-05-04$$d2020-05-06$$eHybrid-OA$$jDEAL$$lDEAL: Springer$$zapproved im dashboard 000875241 909CO $$ooai:juser.fz-juelich.de:875241$$pVDB$$pdriver$$pOpenAPC_DEAL$$popen_access$$popenaire$$popenCost$$pdnbdelivery 000875241 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000875241 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000875241 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000875241 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bEUR PHYS J E : 2017 000875241 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000875241 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000875241 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000875241 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000875241 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000875241 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000875241 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000875241 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000875241 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000875241 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000875241 9141_ $$y2020 000875241 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130885$$aForschungszentrum Jülich$$b0$$kFZJ 000875241 9131_ $$0G:(DE-HGF)POF3-141$$1G:(DE-HGF)POF3-140$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lFuture Information Technology - Fundamentals, Novel Concepts and Energy Efficiency (FIT)$$vControlling Electron Charge-Based Phenomena$$x0 000875241 9201_ $$0I:(DE-Juel1)PGI-1-20110106$$kPGI-1$$lQuanten-Theorie der Materialien$$x0 000875241 9201_ $$0I:(DE-Juel1)IAS-1-20090406$$kIAS-1$$lQuanten-Theorie der Materialien$$x1 000875241 980__ $$ajournal 000875241 980__ $$aVDB 000875241 980__ $$aUNRESTRICTED 000875241 980__ $$aI:(DE-Juel1)PGI-1-20110106 000875241 980__ $$aI:(DE-Juel1)IAS-1-20090406 000875241 980__ $$aAPC 000875241 9801_ $$aAPC 000875241 9801_ $$aFullTexts
