Objective

The objective of the IEA Wind Task MEXNEX(T) is a thorough investigation of the measurements which have been carried out in the EU sponsored Mexico project. Special attention will be paid to yawed flow, instationary aerodynamics, 3D effects, tip effects, non-uniformity of flow between the blades, near wake aerodynamics, turbulent wake, standstill, tunnel effects etc. These effects will be analysed by means of different categories of models (CFD, free wake methods, engineering methods etc.). A comparison of the Mexico findings with the findings of the NASA Ames and other experiments, will also be carried out. As such the Task will provide insight on the accuracy of different types of models and (descriptions for) improved wind turbine models.
