Abstract:

A new approach is shown, which describes the interaction between an active grid excitation and a wind tunnel flow. With this approach we are able to find an excitation for the grid which reproduces an any turbulent flow field. Thereby we can bring free field measurements inside the wind tunnel. The presentation will show how the approach works and comparisons between reference data sets (outside measurements by ultrasonic anemometer) and wind tunnel flow fields generated by an active grid.
