Abstract

The experiments conducted by the authors have showed that the power output of a diffuser-shrouded wind turbine is enhanced significantly by coupling a brim to the diffuser exit plane. This paper presents a simple theory to estimate the power augmentation effect of the brimmed diffuser. The augmentation ratio of inlet velocity and the power coefficient are the functions of the base-pressure coefficient of brim, the pressure recovery coefficient of diffuser and the loading coefficient of turbine. The loading coefficient to provide the maximum power coefficient is linked to the aerodynamic performance of the turbine blade based on the present theory.
