Although helicopter aerodynamics involves the same forces that arise in airplane aerodynamics, these forces occur differently due to fluid flow dynamics across the aircraft. Helicopters take advantage ...

ONE of the most interesting phenomena observed in fluid flow is that of vortex shedding, the best known example of which is the von Kármán vortex street behind a cylinder or similar obstacles normal ...

Recently the flow field around the Savonius rotor has attracted much attention, because the rotor performance is very sensitive to the flow pattern in and around the rotor. Most flow investigations ...

Universal Flow Monitors launched the P420 Series, a set of plastic, vortex-shedding flow rate transmitters designed to process corrosive fluids, water, brine, and low-viscosity fluids in water ...

In the simulations, a tight ring of polar vortices forms at around 55 degrees latitude, the equivalent of Earth’s Arctic circle. After forming, the vortices head toward the poles in a tightening ring, ...
