The shrouded aerogenerator

Abstract

Experimental studies have been performed on a shrouded aerogenerator. The device tested will produce about twice the output power obtainable from an ideal wind turbine working under the same freestream conditions but without a duct. The aerogenerator does not require a driving mechanism that will keep it parallel to the free-stream direction. A simple, two-stage turbine with fixed blade geometry will provide the expected power output over a fairly wide range of free-stream velocities and rotational speeds.
