摘要： This study demonstrates that even when the no-slip condition is satisfied on the surface of a solid wall, apparent hydrodynamic slip can be clearly seen owing to a continuous variation of viscosity associated with density inhomogeneity near the wall. The relationship between the apparent slip length and the local fluid properties, such as viscosity and/or density, has been established theoretically. The apparent slip length depends on the flow type and three cases are considered: shear-driven flow, body force-driven flow, and flow driven by external force acting on adsorbed solutes. Particle-based simulations have been performed and the consistency between our theory and the simulation has been verified. This study demonstrates that even when the no-slip condition is satisfied on the surface of a solid wall, apparent hydrodynamic slip can be clearly seen owing to a continuous variation of viscosity associated with density inhomogeneity near the wall. 其他題名： Soft Matter 出版者： England 出版日期： 2015-01-01 出處： Soft matter, 2015-01, Vol.11 (35), p.6916-692 識別號： ISSN: 1744-683X 識別號： ISSN: 1744-6848 識別號： EISSN: 1744-6848 識別號： DOI: 10.1039/c5sm01627d 識別號： PMID: 26252904
