If you want a good look at 'particles' I'd recommend a textbook and look at the section for submerged bodies in viscous flow.You should have at least a graduate level degree in mathematics.
For automotive work you'll need a super-computer and a fat wallet.After millions of dollars of CFD,automakers are still spending additional millions in the wind tunnel as a backup.

Just doing the best I can to satisfy this questioning mind.
But may I add to that,
in addition, after the wind tunnel there is rigorous road testing to prove the final design, and significant adjustments are often made then too.
