Hey I came into a doubt in the classical physics forums, and I want to know if I said something stupid.
Usually we employ in Fluid Mechanics the adherence condition (u=0 just on the wall, where fluid and solid meets; u=velocity field). But I'm not sure if in turbulent regimenes this keeps on being correct. Sure that boundary layer separates from the wall, or it is formed a turbulent one. Imagine a vortex near wall, do you think I can impose u=0 at the wall?
