Design and Analysis of Diffuser Casings for Diffuser Augmented Wind Turbines

摘要

Diffuser Augmented Wind Turbines (DAWTs) are an efficient method of harnessing wind power compared to conventional wind turbines. This article mainly focuses on the design and analysis of diffuser casing of various with various design parameters. Reynolds Averaged Navier Stokes equations in conjunction with k-$omega$ SST turbulence model was used to analyze the flow pattern and properties through the diffuser casing. The modelling of diffuser was done in CATIA and all CFD analysis was performed on ANSYS FLUENT.
