Different numerical computation methods used to develop a methodology for fast, efficient, reliable design and comparison of Diffuser-Augmented Wind Turbine (DAWT) geometries are presented. The demand for such methods is evident, following the multitude of geometrical parameters that influence the flow character through ducted turbines. The results of the Actuator Disk Model (ADM) simulations will be confronted with a simulation method of higher order of accuracy, i.e. the 3D Fully-resolved

Both will be checked for consistency with the experimental results measured in the wind tunnel at the Institute of Turbo-machinery (IMP), Lodz University of Technology (TUL). An attempt to find an efficient method (with a compromise between accuracy and design time) for the flow analysis pertinent to the DAWT is a novel approach presented in this paper.
