Aerodynamics describes the behaviour of bodies during flow around or through bodies with a compressible fluid. The knowledge of experiments in aerodynamics has a significant influence on the development of means of transport (vehicles, ships, aircraft) and in architecture (skyscrapers, towers and bridges).
It offers – along with its accessories – typical experiments from the field of flow around, incident flow and flow through models, as well as further experiments in the field of steady incompressible flow.
The trainer includes a radial fan, which can be used to generate flow velocities up to 40m/s. The speed is infinitely adjustable by using a frequency converter. A stabilisation tank with flow straightener ensures a consistent, low-turbulence and reproducible flow in the measuring section. A carefully shaped nozzle provides a largely homogeneous velocity distribution of the air flow. The accessory is attached using quick release fasteners and can be interchanged quickly and easily. Measuring points along the measuring section allow pressure and velocity measurements to be taken. The tube manometers are used to show the pressures clearly.
