Foil 23 Why are boundaries important in the discontinuous limit of zero viscosity ?

From CPS615-Physical Simulation Techniques and Structure of CFD Equations Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 14 November 96. by Geoffrey C. Fox *
Secs 119.5
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
