You will be able to simulate rotating wind turbines and mixers with the next release of the Caedium CFD software system. Caedium will support Moving Reference Frames (MRF), which is an efficient way to simulate rotating machinery.

Cycling is one of the fastest sports in the Olympics. With that speed comes an increased importance on aerodynamics. In cycling the aerodynamic design is focused on minimizing drag. However, as with swimming, there are carefully crafted rules that ensure there is only a narrow scope for aerodynamic optimization to gain a competitive advantage.

A big draw of any Olympics is the track and field (athletics) events and no less so in London. What effect is the application of fluid technology to these events likely to have? If past Olympics are anything to go by - not much!
Another helium-filled post - this time it's a helium-filled blimp that houses a horizontal-axis wind turbine [source: gizmag]. Altaeros Energies recently released a video of their prototype Airborne Wind Turbine in action:

Who knew that tetrahedra could fly? I know, pretty much anything can fly when you fill it with helium, but the movement of helium-filled tetrahedra called SmartInversion by Festo gives rise to an interesting and unusual propulsion method [source: gizmag]. Using inverse kinetics, Festo have developed what they call an "airborne geometrical band with inversion drive". The movement is difficult to describe but mesmerizing to watch:

Fishermen at Lake Como, Italy, have shown remarkable knowledge of the complex water currents in the lake. Researchers found [source: Science Mag] that the fishermen's knowledge correlated well with independent observations and Computational Fluid Dynamics (CFD) simulations. The primary means the fishermen use to monitor water currents is by the deformations the currents cause in their large nets once deployed in the lake.
