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.
Simulation of the domain of Badgir
Subtraction of Meshes
The direction of wind at different angles: 0°, 15°, 30° and 45°.
Results for angle 0°.
