A novel high performance diffuser design for small DAWT's by using a blunt trailing edge airfoil
Arturo Alanís, Jesus Alejandro Franco, Saul Piedra and Juan Carlos Jauregui

 
Abstract
    This paper proposes a novel diffuser design for Diffuser Augmented Wind Turbines (DAWT) based on the blunt trailing edge airfoil AF300. Computational Fluid Dynamics (CFD) simulations are carried out to measure the performance of the AF300 diffuser against diffusers made with the shape of other high performance low wind speed airfoils. The results show that the proposed diffuser produces a greater air mass flow increase through the plane of the turbine than the other diffusers and it can be used to increase the performance of a horizontal axis wind turbine.
