牛顿流体在固体壁附近的流速的边界条件已被实验探测与一个新的设置使用全内反射荧光恢复后，光漂白导致从壁的分辨率的顺序为80 nm。对于十六烷流动的烃/疏液光滑表面上，我们给我们认为是第一个直接的实验证据，明显的滑动在墙上。我们表明，表面粗糙度和流体表面相互作用的强度都作用于壁面滑移，在拮抗剂的方式。
The boundary condition for the flow velocity of a Newtonian fluid near a solid wall has been probed experimentally with a novel setup using total internal reflection-fluorescence recovery after photobleaching leading to a resolution from the wall of the order of 80 nm. For hexadecane flowing on a hydrocarbon/lyophobic smooth surface, we give what we think to be the first direct experimental evidence of noticeable slip at the wall. We show that the surface roughness and the strength of the fluid-surface interactions both act on wall slip, in antagonist ways.
