Abstract
Velocity slips may occur as a fluid flows over a solid surface in the nanometer scale. The slip length , characterizing the degree of slip, is usually used to describe the velocity boundary condition at the fluid/solid interface. In this work, we show that for a given wall-fluid system, the slip length generally varies with the system temperature . In particular, we show that it is possible to create a pair of solid wall and fluid systems, in which the velocity slip becomes rather small and independent of temperature.
