Abstract
We have developed a shrouded wind turbine with a brimmed-diffuser. To realize higher power augmentation of it, we have investigated the optimum parameters of the diffuser angle and hub ratio, and the optimum shapes of the inlet shroud and center body. As a result, the new wind turbine has demonstrated power augmentation for a given turbine diameter and wind speed by a factor of about 5 compared with a bare wind turbine.
