Abstract
The flow of fluid into energy capture machines is crucial for determining the amount of energy extracted, particularly in the field of renewable energy resources. The current invention describes devices and methods for applying the physics of flow to energy capture machines, most commonly wind and water turbines, by enhancing the flow into the energy capture component by the appropriate placement of various objects called flow deflection devices (FDD). FDDs can make a highs significant improvement in power output.
