Validation of Navier-Stokes 2D

[wdeconinck]

• Depends on finishing of Implementation ( issue Implement Navier-Stokes 2D #2 )
• Basic tests will be performed by @wdeconinck to see if results "look" okay.

Validation for laminar flow:

• Cylinder
• Flat plate

Interesting article:
Joe Iannelli : "An exact non-linear Navier–Stokes compressible-flow solution for CFD code verification" , 2012

It provides an analytical solution for the 1D compressible Navier-Stokes equations. It claims to be capable for multidimensional space discretization verification through rotations.

I have read the summary and it seems very interesting. However, Iannelli uses 1D NS with shock.
That means we need limiter. As Willem knows I have green blinking light next to limiter in our agenda but we have no scheduled this job yet. If Iannelli presents also exact solutions without shock I think we have to use his solution to validate 1D NS.
