We have developed a new wind turbine system that consists of a diffuser shroud with a broad-ring brim at the exit … periphery and a wind turbine inside it. The shrouded wind turbine with a brimmed diffuser has demonstrated power augmentation by … inside the diffuser shroud. …

To clarify the behavior of the blade tip vortices of a wind turbine equipped with a brimmed-diffuser shroud, called a … unique wind turbine consists of not only rotating blades but also a diffuser shroud with a broad-ring brim at the exit … the blade tip and the inner surface of the diffuser. Since these vortices interacted with each other, the blade tip vortex …

A new class of diffuser augmented wind turbines (DAWTs) is presented. The new diffuser concept exploits aero … potentials which exceed the power efficiency based on the diffuser exit area by 50%. The paper presents the 1D momentum theory …-Axis Wind Turbines (HAWTs). Inviscid axisymmetric panel code calculations are then used to drive the diffuser design towards …
