Learning With the Flow

The bigger the swirl, the bigger the problem — and the bigger the computing power needed to solve it. Computational fluid dynamics researchers have spent decades studying how liquids and gases flow in and around such machinery as airplane wings, propeller blades and jet engines in search of faster speeds…
