I'm concerned about how to validate your CFD simulation. Here are some ways I know:
1. Compare simulation results with experimental/analytical results if available.
2. If no experimental/analytical results to compare with, run simulations with different mesh, models using explicit/implicit method,....and the results shall stay unchanged.
More suggestions?

Another way is to use the method of manufactured solutions like those proposed by Roache, P.J. (2002).

Good luck...

Derive the analytical solution for 3D Navier-Stokes equation and collect 1 Million $.

Actually, to win the prize, you "just" need to prove that strong solutions do not exists for any fixed time and Re number...which is more likely the case.
