Foil 31 Why are boundaries important in the discontinuous limit of zero viscosity ?

From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox

when viscosity m = 0

Boundary condition is that velocity must // to surface

when m is nonzero

Boundary condition is full v = 0 at surface (parallel and perpendicular components zero)

Note: As equation goes from first to second order when m = 0, need an extra boundary condition
