Slip Flow Boundary Condition in Liquids

The liquid slip phenomenon has been presented in the following sections. The experimental investigation quantifying the liquid slip has been discussed to begin with followed by the results from molecular simulation. Subsequently, the factors responsible for liquid slip and the possible mechanism responsible for liquid slip are discussed. 

The applicability of slip flow is not well accepted to date by the academic community. One of the problems is the small length scale of slip flow regime (if present) in comparison to the length scale of the flow or system. The hydrodynamic boundary condition appears to be one of no-slip, unless the flow is examined on a length scale comparable to the slip length. Hence, very accurate techniques with high spatial resolution, capable of interfacial flow measurements, are required to detect the effects of slip. Some of the examples of slip flow in liquid are reviewed in the following section.
