Hanot, S.Belushkin, M.Foffi, G.2013-03-282013-03-282013-03-28201310.1039/c2sm26316ehttps://infoscience.epfl.ch/handle/20.500.14299/91034WOS:000311964200033The understanding of the exact boundary conditions at the interface between a solid and a fluid is becoming increasingly important, as the limitations of the no-slip boundary condition are becoming apparent, especially in micro- and nanofluidics applications. We present a systematic study of controlled partial-slip boundary conditions in multiparticle collision dynamics simulations. By studying a plane Poiseuille flow, we demonstrate that, in general, the slip length of the fluid strongly depends on the microscopic dynamics in the vicinity of the solid surface. We empirically derive the dependence of the slip length on the properties of the MPC fluid and of the wall, and demonstrate that the wall slip in this coarse-grained simulation approach is linearly correlated with the flux of momentum across the fluid-solid interface.text::journal::journal article::research article
