An active slat on an airfoil is tested in the wind tunnel to reduce lift fluctuations caused by inflow angle fluctuations. The airfoil with an integrated slat allows to control the gap size between slat and main body. The variation of the gap size le

As wind energy turbines are getting larger, the blade root bending loads are becoming a design constraint. Especially loads resulting from the increasing blades masses as well as from turbulences, gusts and even local stall at the inner blade section

The aeroacoustic effects of the flow around a cylinder with a small rectangular cavity in its surface are investigated in an acoustic wind tunnel. In different positions, the overflown cavity produces loud tonal whistling noise. In large part, the no

The intensity and phase reconstructed from digital in-line holograms by the convolution approach are analyzed. Distortions of particle images depending on their position in the plane transverse to the optical axis are identified. For this purpose, th

In digital holographic particle image velocimetry, hologram truncation is a very prominent problem when the projection of the particle position to the sensor is close to the sensor edge. Using the convolution approach to reconstruct such a hologram y

Cavity noise generation is of particular interest for e.g. the aeronautical and automotive industry where a lot of different shaped cavities occur on curved surfaces. In this work the flow over a small rectangular cavity (L/D ≈ 1) on a cylinder at

A digital holographic in-line setup was used to track particles in a small turbulence chamber. Different particle validation methods have been tested to filter out speckles and to enhance accuracy of the longitudinal particle coordinates. In first me
