Rotor Design for Diffuser Augmented Wind Turbines
Diffuser augmented wind turbines (DAWTs) can increase mass flow through the rotor substantially, but have often failed to fulfill expectations. We address high-performance diffusers, and investigate the design requirements for a DAWT rotor to efficiently convert the available energy to shaft energy. Several factors can induce wake stall scenarios causing significant energy loss. The causality b...
متن کاملApplication of a Diffuser Structure to Vertical-Axis Wind Turbines
The effects of using a wind acceleration device (wind lens) with vertical-axis wind turbines in wind tunnel experiments were examined. A wind lens consists of a diffuser and flanges, and this study investigated the optimum parameters of their configuration with regard to the power augmentation of the turbines. The wind lens with a flat-panel-type diffuser demonstrated power augmentation by a fa...

متن کامل41.3 Wind Turbines
The development of windmills has a long tradition. Windmills were already in use in Japan and China thousands of years ago. The great irrigation systems of Babylon are thought to have been powered by windmotors. Examples of windmills erected almost 2000 years ago still exist in Egypt. 'Wind power generation was first introduced to the Western world around the 8th century A.D. By the 16th centur...
