Several tests have been conducted on scale models of a Badgir
La soufflerie de l'IUT de Ville d'Avray, Université Paris-Ouest.
This model was designed specifically to be tested in the wind tunnel.
Connection for pressure measurements.
Final model
Description of the wind tunnel
The performancesthese from the wind tunnel
50m/s
Test Area: 450*450*700
1% turbulence intensity
Installation of pressure measurement and air extraction points along the ducts
We drilled 140 holes evenly spaced along the ducts to allow pressure measurement and air extraction.
Measuring device
The yellow liquid makes it possible to visualize the reaction of a conduit to the prevailing wind.
Diagram of the operation of the blower
The mouth of the wind tunnel propels the wind at a speed of 20 m/s (chosen according to the resistance of the model). The pipes connected to the orifices transmit the pressure variations to the measuring devices.
Wind direction tests at angles of 0°, 15°, 30° and 45°
