Default difference between const and sutherland transport model in thermophysicalproperties

Hi all foamers,

Currently I am working on a hypersonic flow case with a double wedge. I have validated the laminar case with a inviscid condition, now moving on to laminar viscous. However, when I modified the mu from 0 to 1.2777e-5 with the transport model const, the boundary layer barely developed and no separation bubble between two wedges. I have double checked the bc of the surface of the wedges, which I defined to fixed value (0 0 0) since noSlip does not seem to work when I was trying to view it in Paraview. I would like to know whether switching to sutherland will solve this problem?

Thanks!

Please elaborate on "no slip not working when viewing in paraview". No slip has been successfully applied to many of us here.
