Wind tunnel
The Institute of Applied Thermo- and Fluiddynamics has a Göttingen type wind tunnel with an open measuring section at its disposal for aerodynamic measurements. The wind tunnel is used to investigate the behavior of components and assemblies under the influence of wind. A frequent application is the determination of aerodynamic forces acting on a component under wind load. Probably the best-known application examples are wind tunnel investigations on airplanes and cars. Due to the dimensions of the available wind tunnel, however, such measurements are only possible on a model scale, taking into account the similarity mechanics.
In principle, the wind tunnel consists of a blower, pipes for air routing, a nozzle, the measuring section and a collecting diffuser. A Göttingen type wind tunnel is characterized in particular by the fact that the air is captured by a diffuser after the measuring section and then fed back to the blower. The main advantage of a wind tunnel of this design is that the power requirement of the blower is significantly reduced and higher flow speeds can be achieved.
