I No Slip condition in an Inviscid Fluid

  1. Aug 11, 2017 #1
    In an Inviscid fluid would the no slip condition exist?
    If it didn't would it follow that the free stream velocity would exist at the wall ?.
    If this was the case would surface roughness still present an orthogonal area upon which the kinetic energy of the fluid would interact causing a momentum change ?

    No, the no slip condition does not exist in an inviscid fluid. The velocity at the wall would depend on the shape of the wall. If it was a flat plate, then yes, the velocity at the wall would be that of the free stream.
