Boundary conditions at viscous flow
Dear all,
I make a code for Navier-stokes equations but, I confuse about the boundary conditions at the viscous flow particularly at the outflow boundary for example, at supersonic outflow, when I do the Euler equations, there's no problem. all properties extrapolated. but how about Navier-Stokes? in the region near the wall is subsonic, then I have to specified 1 property or no? Please somebody help me, thank for your information :) |
