The ventilation and cooling in the traditional architecture of the Persian Gulf

History devices, modeling, performance evaluation.

Wind Tunnel of Ville d'Avray

Velocity, pressure and extraction of every conduit were captured using a laser Doppler anemometer.

The model used in the wind tunnel with breakthrough wall for pressures analyzes.
Description of the wind tunnel
In this experiment, we used a subsonic Prandtl wind tunnel

 

50 m/s

Test Area : 450*450*700

1% turbulence intensity

Connecting the model

 

140 openings were carried out with a regular interval in order to connect the pipes to measuring device.

Measuring device

 

The yellow fluid shows how a conduit acts against the prevailing wind.

Operation of the wind tunnel

 

The wind tunnel sends wind to 20 m / s. Each pipe connected to the piercing transmits pressure or extraction to the measuring device.
