Technical Description The educational wind tunnel is a so-called "Eiffel type" of open subsonic wind tunnel..
With this type of tunnel the air is taken from the atmosphere and
returned to the atmosphere. A carefully designed nozzle shape guarantees
the constant distribution of velocity within the closed measurement
section. Velocities of around 100km/h are reached. A flow rectifier at
the inlet ensures a low degree of turbulence. The wind tunnel consists
of the following components: inlet hopper with flow rectifier, nozzle,
measurement section, diffuser and fan. The nozzle, inlet hopper and the
measurement section are mounted on a guide rail and can be moved in
order to access the measurement section. An axial fan with guide wheel
is used which is characterised by its low noise level and high
efficiency. The fan is mounted on rubber elements to minimise vibration
during operation. It is driven by a speed-controlled motor with
frequency converter. The fan is connected permanently with the diffuser.
An electronic 2-component force transducer permits the measurement of
resistance and buoyant forces at various objects. The measured values
are displayed on a measuring amplifier. It is also possible to process
the data via PC-data acquisition (available as an accessory). A slanted
tube manometer is used to display the current air velocity at the inlet
into the measurement section. luid Mechanics Lab Equipments
