What have you tried? There is a simple example in the What's New in Mathematica 10, just plug into the Navier-Stokes instead of pure Stokes flow. –  m0nhawk Aug 15 at 7:25

This blog is a good start:

Using Mathematica to Simulate and Visualize Fluid Flow in a Box

It fully solves 2D problem of one moving boundary

and gets nice vertex flows:

There are detailed descriptions of proper equations and numerical discretization. You can generalize to 3D. I would look also in latest V10 functionality to see if anything can be used there to upgrade the methods of the blog - it was written before V10 came out. For instance, take a look at this Stokes Flow example which is a simplification of NS:
