Description

This project uses ANSYS Fluent to study how dust particles enter a room through windows and move/deposit inside. The 3D geometry (DesignModeler) represents a room with two windows and a chimney. Meshing (ANSYS Meshing) yields 42,061 elements. Because deposition evolves over time, the simulation is transient.

Dust Particles Methodology

Dust-laden air enters via the two window inlets at 0.25 m/s and exits through a pressure outlet at the chimney top. Particle transport and settling are modeled with a two-way coupled Discrete Phase Model (DPM) to capture interaction between the particles and the carrier flow. The laminar flow model is used for the continuous phase.

Conclusion

Outputs include 2D velocity contours, vectors, and streamlines, revealing airflow paths and dust motion. The wind-driven flow carries particles along the main stream, while recirculation zones promote enhanced deposition and sediment accumulation.
