Abstract |
|
Flanged Diffuser is collecting-accelerating device which shrouds a wind turbine. For given turbine diameter, the power augmentation can be achieved by brimmed diffuser, popularly known as wind lens. The present numerical investigation deals with the effect of low Pressure region created by wind lens & hence to analyze the strong vortices formed by brim attached to shrouded diffuser at the exit. Also in this analysis, a comparative numerical prediction of mass flow rates the wind turbine has been carried out with various types of wind lens which in turn helps to optimize the torque augmentation. It has been proved that there is significant increase in the vortex strength & wake formation when brimming effect is added to a diffuser. |
