All,

In inviscid, incompressible but not irrotational flow, is it possible for a vortex line to touch a solid wall ? The wall has a slip condition of v.n = 0.

Thanks,

Sam

From the Chorin's textobook


"A vortex tube with nonzero strength cannot "end" in the interior of the
fluid. It either forms a ring (such as the smoke from a cigarette), extends to infinity, or is attached to a solid boundary. "
