摘要
We studied solid-liquid slip by a mean-field free-energy lattice Boltzmann approach recently proposed [Phys. Rev. E 69, 032602 (2004)]. With a general bounce-back no-slip boundary condition applied to the interface, liquid slip was observed because of the specific solid-fluid interactions. Our work relates, interfacial slip to a more realistic solid-fluid interaction and hence contact angle. The kinetic nature of LBM is manifested in this interfacial study. A small negative slip length can also be produced with a stronger solid-fluid attraction.
