Abstract
We developed a new wind turbine system that consists of a shrouded diffuser with a broad-ring brim at the exit periphery and a wind turbine inside it. We are now researching for larger scales of this wind turbine. In view of practical point, we must develop a more compact shrouded wind turbine. To investigate the optimal shape and length of this diffuser shroud with a brim, wind tunnel tests are employed. The shrouded wind turbine equipped with compact brimmed diffuser demonstrates a remarkable power augmentation compared with a bare wind turbine.
