Preparing for the breaching, project officials spent years calculating volumetric flow rates, fluid dynamics, deterministic hydrologic modeling and other scientific and engineering factors all designed to predict what the rivers would do when released, to prevent the mine wastes from being scoured and to minimize damage to the environment as the rivers are brought back to their natural state. It's gone even better than expected, said Russ Forba, the EPA's Milltown project manager. (Missoulian, MT)

World's 'fastest' swimsuit developed Mar 3, 2008
Researchers claim to have developed the world's fastest swimsuit, using a specialised computer modelling technique called Computational Fluid Dynamics (CFD). "CFD is used to help us gain an idea of the sources of skin and form drag (which is due to the presence of one's body travelling through the fluid). Skin drag is inherent to the material properties over which a fluid flows and to the local flow conditions (speed in particular) as it is induced by the local velocity gradients. "With CFD...
