Ilmenau barrel
Ilmenauer Fass is the name of the world's largest installation for investigating turbulent convection currents with the highest relative measurement resolution. The facility is located outside of Ilmenau in the Schortetal on the grounds of the Volle Rose mine .
properties
With a diameter of 7.0 meters and a height of 6.3 meters, the Ilmenau barrel is the world's largest Rayleigh-Bénard experiment for studying highly turbulent convection currents in air. In the inner area of the arrangement, an almost homogeneous and isotropic turbulence can be generated, which is free from artificial mechanical excitation. Velocity and temperature fields can be measured almost unrestrictedly with a unique spatial and temporal resolution. There is also modern flow measurement technology, such as B. 3D-Laser-Doppler-Velocimetry, 3D-Particle-Tracking-Velocimetry, 2D-Particle-Image-Velocimetry , multi-channel temperature measurement system with micro-thermistors are available.
