Description

This problem simulates the Internal Airflow inside an Atrium located in a complex by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The history of the atrium originates from the architecture of ancient Roman houses. Its modern models in recent centuries are multi-story. They have a glass roof and a set of windows that are usually located immediately after the main entrances of the buildings.

This part of the building is used to provide the necessary light for the interior of the building as well as building ventilation.

In the present case, the cylindrical area called the atrium in the central part of a complex is considered; So that the airflow at the velocity of 2 m/s and the pressure of 101325 Pa enters the complex from the lower entrance and exits the interior space of the atrium from the upper entrance.

Internal Flow Methodology

The present model is drawn in three dimensions using the SpaceClaim software. The current model consists of a building area of a large complex with a cylindrical space called the atrium inside the complex.

The meshing of this model has been done using ANSYS Meshing software. The mesh type is unstructured, and the element number is about 2500000. The cells adjacent to the internal boundaries are smaller and more accurate.

Internal Flow Conclusion

This project aims to investigate the behavior of airflow inside the atrium and study the pressure and velocity distribution of the internal flow inside the atrium.

After the solution process is complete, two-dimensional and three-dimensional contours related to pressure, velocity, pathlines, and velocity vectors are obtained. So the zones with the optimum pressure and velocity comfort can be obtained easily.
