Dear all,
I am hereby to get advices.
My research topic is appointed to be slip flow measurement. I have read a lot of papers in this area. So far, there is no clear physics definitions on slip length and slip velocity, which are from micro viewpoint instead of macroscale. And there is no convincing experiment result, in fluid dynamics area, to clearly prove the existence of non-slip boundary condition for Newtonian fluid. Some physics researchers use Atomic Force Microscope to measure the hydrodynamic resistance force between the tip and the substrate, and they draw some conclusions on slip length. The measured slip length is at nanometer scale, it is comparable with surface roughness. I am aimless now. Should you have any experience or ideas on this topic, please share or talk with me. Thanks.
Cecil
