Hexadominant method...

I agree with "Far", but don't recommend the Hexadominant method for CFD.
The Hexadominant method starts by paving quads at the walls and then marches inward with isotropic hexas which can crash somewhat badly in the middle. This is good for FEA structural analysis where most of the interesting stuff happens near the surface and uniform elements are sufficient to capture it all, but it is not good for CFD.
However, if you tried Multizone (or sweep) with an inflation layer, you could get a nice combination of swept hexas that would produce a good mesh for CFD.
