Description

Description

The problem simulates the wind flow through several buildings in a specific computational domain by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

These buildings are considered barriers to airflow. The flow around the obstacles in the path of wind flow, such as the flow around buildings, aircraft wings, ship’s propellers, rigs, tall structures, etc., has many engineering applications.

In the present case, the wind flow around the three buildings is considered where the airflow enters it horizontally at a speed of 5 m/s and hits the buildings. This study investigates airflow behavior around buildings after colliding with them and studies the vortex phenomena behind these buildings.

Wind Methodology

This simulation is transient, and the whole simulation process is done in one second with a 0.01 s time step size. The present simulation is unsteady in terms of time because the purpose of the problem is to examine the effect of wind flow on structures over time. The Pressure-Based solver has been performed.

The present 3-D model is drawn using the Design Modeler software. The current model consists of an extensive computational domain in a rectangular cube with dimensions of 120 m ⨯ , 300 m ⨯ , 100 m, and three tall buildings within this domain with a height of 75 m.

The model meshing has been done using ANSYS Meshing software, and the mesh type is unstructured. The element number is 128893, and the cells adjacent to the buildings are smaller and more accurate.

Wind Conclusion

At the end of the solution process, based on the contour related to pressure, the maximum pressure happens when the wind flow collides with the front sides of the buildings.

Also, from the velocity contours, it is visible that the vortex occurs on the backward faces of the buildings. Turbulence kinetic energy, pathlines, and vectors are also extracted and analyzed. All contours, pathlines, and velocity vectors are obtained in the final second of the solution process, after 1s.

    Woowww! Amazing

    How does the simulation model the wind flow around the buildings?

    • MR CFD Support

      The simulation uses the k-epsilon turbulence model to simulate the turbulent nature of the wind flow around the buildings.
