Abstract
The aim of this work is to analyze the influence of the pressure losses of a Diffuser-Augmented Wind Turbine (DAWT) on the extractable power. Multielement diffuser geometries, generated with Salome and meshed with snappyHexMesh, are studied numerically with OpenFOAM\(^{\textregistered }\) to find a configuration of maximum area expansion (reducing flow detachment), for different pressure losses at the actuator disk. Different geometries are studied with a \(k{-}\varepsilon \) turbulence model. The influence of the vanes inside the diffuser has also been analyzed. The results of the present work show the importance of a careful design of the diffuser entrance.
