Abstract

An experimental study was performed on a full-scale DAWT to understand its response behaviour to changes in wind speed fluctuations. A novel diffuser was designed from the results of previous numerical studies and was manufactured using lightweight materials. The resultant DAWT was made portable and tested in three wind directions. Wind speeds, wind directions and output power was recorded from both the bare wind turbine i.e. before it was applied with the diffuser and then the resultant DAWT. From experimental testing of the DAWT, wind speeds to the rotor were increased by 136% from 1.02 m/s to 2.41 m/s. The augmentation ratio was evaluated at 8.32 and the DAWT exhibited better responsive behaviour than the bare wind turbine in terms of matching the expected output power profile and a smaller response time.
