The low speed wind tunnel MUB is a closed return atmospheric tunnel (Göttingen-type tunnel) with modular test sections. The larger 1,3 m x 1,3 m closed test section can be operated at a maximum speed of 60 m/s. We have different force balance and pressure scanning systems available to measure most aerodynamic quantities. For the quantitative visualization of flow fields we routinely use our full range of experimental methods in the MUB.
The MUB is a multi-purpose 'Göttingen type' wind tunnel with exchangeable test sections for manifold research on e.g. airfoils, aircraft components or ground vehicles. The test sections are closed and largely modular in design in order to realize a wide variety of experiments. They allow various optical accesses and a wide range of measurements. A heat exchanger in the settling chamber allows stabilization of the flow temperature. Furthermoer, the settling chamber houses a flow straightener and three turbulence meshes to optimize the flow quality. The contour of the nozzle is also optimized for the lowest degree of turbulence and best uniformity. The wind tunnel thus allows sophistiated measurements, such as investigations of laminar-turbulent transition.
The two closed test sections have different size to allow different flow conditions for the test objects. Larger Reynolds numbers and better flow quality can usually be achieved with the larger test section. Both sections allow flexible, optical access through easily movable and exchangeable walls.
All necessary components exist for numerous set-up variants: Two-dimensional (airfoil) models can be mounted between turntables in both test sections. Models of finite elements (wing tips, winglets, half models) can be installed on a rotating floor with balance support. For investigations on automobiles, an additional ground plane with flow splitter is used to reduce the thickness of the ground boundary layer.
A gust generator, as well as various secondary equipment (suction systems, compressed air supply) are available for the wind tunnel.
Our entire range of experimental methods is routinely used in the wind tunnel.
