The EA102 blower is of the two-dimensional parietal jet type and
allows the study of the development of the boundary layer on a flat
plate. With the plate removed, one can also study the flow of a
two-dimensional free-plane jet and calibrate a hot-wire anemometer.
Technical description :
A centrifugal fan is mounted inside a plenum. It is equipped with a
rechargeable filter, a honeycomb for straightening the flow and a
fine mesh grid to reduce residual turbulence.
A two-dimensional plexiglass convergent, with a contraction ratio
of 30, ensures a good homogeneity of speed at the outlet of the
jet.
A simple air bypass valve system provides progressive and precise
adjustment of the jet outlet speed.
The jet is channeled by two vertical walls in transparent
plexiglass. One of the two walls, mounted on hinges, provided with
a blocking device in the open position, facilitates the
interventions inside the test vein.
A traversing device, consisting of a carriage mounted on ball
bearings, can be moved along the test line. Its positioning is
carried out using an index and a graduated scale fixed on the frame
of the test vein.
The traversing device allows the vertical displacement of the
probes in the median plane of the test vein. The positioning of the
probes is carried out thanks to a graduated vernier. A quick
fastening device allows the assembly of probes of different
diameters.
A boundary layer probe is provided as standard.
