Dust Particles Entering the Room, Ansys Fluent Training

Description

The present study investigates the dust particles entering from the windows into a room by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The present model is designed in three dimensions using Design Modeler software. The geometry for analyzing this simulation consists of a room in which 2 windows and a chimney exist.

The meshing of the model has been done using ANSYS Meshing software. The element number is 42061. Also, due to the nature of the problem, the transient solver has been enabled.

Dust Particles Methodology

In this project, the dust particles entering the building at a velocity of 0.25 m/s are examined, and the house’s sedimentation and dust movement are depicted. To simulate the sedimentation process discrete phase model is used.

Also, a two-way DPM model is used to examine the behavior of particles moving inside the room accurately.

The airflow enters the domain through inlet boundaries (i.e., the two windows) and brings particles inside the room; then, it leaves the room through the pressure outlet boundary considered on the top side of the chimney. Moreover, the laminar model is used to solve the fluid equations.

Dust Particles Conclusion

At the end of the solution process, two-dimensional contours related to the velocity, velocity vectors, and streamlines inside the room are obtained. We can see from the contours, the airflow, and the movement of the dust.

The flow created by the wind speed carries the dust in the direction of the flow. As a result, dust in areas of vortex formation may have more sediment.
