Pollution Treatment in Cement Industry CFD studies are vital for protecting the health of workers and nearby residents. Cement factories release a lot of dust and harmful particles like CO2 and NOx. If we design buildings near these factories incorrectly, they can act like traps, collecting dangerous dust on balconies and in corridors.

Engineers use pollution DPM ANSYS Fluent simulations to solve this problem. We simulate how dust travels in the wind around different building shapes. By using the Discrete Phase Model (DPM), we can track millions of tiny particles. This report compares two building forms (Design A and Design B) to see which one stays cleaner. This Pollution Treatment CFD simulation helps architects create safer environments where wind naturally flushes away pollutants instead of letting them settle on the structure.

Simulation process: Wind Profile UDF and DPM Configuration in Fluent

The simulation process for this Pollution Treatment in Cement Industry CFD project focused on accurate geometry and particle physics. We created two different building designs (Form A and Form B) and placed them in a large air domain. To capture the complex shapes of the building corners and balconies, we generated a high-quality unstructured tetrahedral mesh. The total grid count is 427,511 cells. This fine mesh is very important for pollution DPM ANSYS Fluent calculations because it allows us to see exactly where the wind hits the walls.

We used the Discrete Phase Model (DPM) with 1-way coupling. This means the wind moves the dust, but the dust is too light to change the wind direction. To make the simulation realistic, we wrote a code called a User Defined Function (UDF). This UDF creates a real wind profile where the air moves faster at the top of the building and slower near the ground. We injected dust particles ranging to represent cement byproducts. This setup allows the Pollution Treatment CFD simulation to predict if the particles will fly away or stick to the building surfaces.

Post-processing: Particle Deposition and Architectural Efficiency Analysis

The post-processing analysis provides a critical engineering comparison between the two building forms. We must look at the data to see which design is “cleaner” and safer for people working in the cement industry. The most important achievement is found in the Total Particle Mass data. The data in Table 1 shows a huge difference. Design A (the first building form) accumulates a Total Particle Mass of 1.089851 kg. This is a high amount. It means the building shape traps the dust. The average concentration is 3.36 x 10⁻⁶ kg/m³. In contrast, Design B is much better. It accumulates only 0.161259 kg of dust. This is approximately 85% less pollution remaining on the building compared to Design A. The average concentration is slightly higher (4.43 x 10⁻⁶ kg/m³), but the low total mass proves that the wind successfully washes the dust away.

Why is Design B cleaner? The Velocity Contours (Figures 4 and 5) explain the physics. In Design A, the contours show large stagnant zones (0-3 m/s) behind the walls. These are “dead zones.” When dust enters these slow areas, it falls out of the air and lands on the floor. This explains the bright colored spots in the Particle Concentration Contours (Figure 3), which show heavy dust buildup. However, Design B has better aerodynamics. The velocity contours show that the wind maintains a higher speed (4-8 m/s) as it passes through and around the structure. There are fewer dead zones. The wind acts like a broom, sweeping the cement particles out of the building area. For a designer, this Pollution Treatment CFD simulation confirms that Design B is the superior choice. It uses natural wind flow to “self-clean,” ensuring that hazardous dust does not settle where people walk and work.
