Wind tunnel rotor measurements
bookPart
To investigate the effects of rotation without the complicating effect of unknown stochastic inflow, wind tunnels have been used for 3D rotating measurements despite their size limitations. Several examples of past experiments and their lessons learned are given, illustrating the challenges with respect to scaling and measurement instrumentation. An outlook to the future is given anticipating on the further development of instrumentation to quantify aerodynamic loads and flow on smaller scales. Developments to reproduce more realistic inflow conditions in a controlled way are expected to further close the gap between wind tunnel and field measurements. To further drive down the costs of wind energy there is a large need to perform aero-elastic and high Reynolds number testing in a controlled rotating environment.
