Numerical analyzes of mechanical behavior of Badgirs, CFD (Computational Fluid Dynamics)
The aerodynamic aspects are examined numerically by using FLUENT. The numerical method employed for this research is based on a 3D finite volume method.
FACTORS CONSIDERED IN THESE CALCULATIONS: Different wind speeds; different temperatures; different wind incident angles; humidity; building materials (clay soil); thickness of the walls; full and empty fountain; location openings and different surfaces.
We designed a model to perform tests and numerical analyses.

The direction of wind at different angles: 0°, 15°, 30° and 45°.
Results for angle 0°.
Results for angle 30°.
The pressure is negative in channel B, C and D. Maximum velocity in channel A.
