# 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 analyzes.

The 3D drawing destinated to defining Boundary conditions.

###### The direction of wind at different angles: 0°, 15°, 30° and 45°.

Results for angle 0°.
