## Description

The problem simulates sand particle sedimentation in a water flow channel using ANSYS Fluent software.

The sedimentation phenomenon is one of the destructive phenomena in the quality of performance of any equipment. Sedimentation can occur when the base fluid contains excess soluble particles.

The discrete sand particle’s diameters are variable, including a minimum diameter of 0.00001 m, a maximum diameter of 0.0002 m, and an average diameter of 0.000131 m. The present model is designed in three dimensions using Design Modeler software.

The model consists of a computational area in the form of a horizontal channel with a square cross-section in which the flow of water and particles move horizontally inside.

On the lower surface of the canal, three rows of plates or diagonal barriers are designed that can help the sedimentation phenomenon.

We carry out the model’s meshing using ANSYS Meshing software, and the mesh type is structured. The element number is 14280.

## Sedimentation Methodology

In the present simulation, the Eulerian-Lagrangian perspective on computational fluid dynamics (CFD) is used; So that the Eulerian multiphase model is coupled with the dense discrete phase model (DDPM).

A continuous phase is defined, related to water flow, and a discrete phase is described, related to sand particles. The material of sand is defined as stagnant particles with a density equal to 2650 kg/m3.

The water flows with a flow rate of 15 kg/s and enters the channel horizontally. Simultaneously, the flow of sand particles enters the channel discretely with a flow rate of 0.21 kg/s and a velocity of 0.083 m/s.

## Sedimentation Conclusion

Water flows along with sand particles into a canal, and the channel has obstacles in its path, or there is a sudden change of direction within the channel; a sedimentation phenomenon occurs; Because in areas with obstacles and with a sudden change of direction, dissolved sand particles locally relative to the main water flow becomes stagnant and slows down.

At the end of the solution process, two-dimensional contours related to water pressure and velocity and three-dimensional contours related to water pressure and velocity, and a particle sequence based on the residence time and particle diameter are obtained.

For example, the particle sequence indicates that water-soluble particles accumulate in the front area of ​​the barrier after hitting the initial oblique barrier. Thus, the sedimentation phenomenon is possible.

2. Prof. Kamren Johnston DDS

Is it possible to scale the simulation up for more complex urban sewer systems with varying diameters and flows, or would this require significant adjustments to the methodology used?

• MR CFD Support

The current methodology can serve as a foundational approach for scaling up to more complex urban sewer systems. One would need to consider the specific geometric configurations, variable diameters, and different flow rates for a more detailed model. Additional adjustments to the methodology could include refining the mesh for larger systems, implementing advanced turbulence models if required, and calibrating the sediment particle parameters based on the characteristics of the specific urban sewers being studied.

This course sounds useful! Does the training include lessons on how to interpret the data obtained from these simulations, like understanding the particle sequence and its significance?

7. Joel Okuneva

I’m very interested in learning how the sedimentation process works in urban conduits. Does the course provide visualizations that show where sediment accumulates and how it affects the water flow?

• MR CFD Support

Yes, the training provides detailed visualizations. You can observe two-dimensional contours of water pressure and velocity, as well as three-dimensional contours, which help in identifying where the sediment settles and how it interacts with the water flow. These visualizations reveal the sediment accumulations, especially after the water-soluble particles encounter the barriers placed within the channel, facilitating your understanding of the sedimentation dynamics.

8. Zena Roberts

Is it possible to simulate the settling of heavier particles, like gravel, in addition to sand, using the same setup and methodology?

• MR CFD Support

While the methodology for sedimentation analysis utilizing Eulerian-Lagrangian method is consistent, the simulation of heavier particles like gravel would require an adjustment to the discrete phase properties including particle density, diameter, and perhaps the inlet velocity to reflect the behavior of gravel during sedimentation. It’s practical to use the same general setup, but parameter tuning is indeed necessary for accurate simulation results.

9. Kameron Hegmann PhD

Your product gave a detailed explanation, but could you tell me if the impact of the particulate shape was considered in the sedimentation simulations?

• MR CFD Support

In the sedimentation simulation using ANSYS Fluent, the standard model primarily accounts for the size and density of the particles. While particle shape can be important, this specific simulation assumes spherical particles, as is common in CFD. This simplification is often used to reduce complexity and computation time when the goal is to understand overall trends and the impact of sedimentation.

12. Steve Zemlak

This analysis appears to be very complex. The way the sand particles settle must be intriguing to observe. Could you provide more details on how the DDPM-DPM coupling is managed in the simulation?

• MR CFD Support

In the simulation, the DDPM-DPM coupling integration allows for calculating interactions between the continuous water phase and the discrete sand particles. The Eulerian approach represents the water as a continuous phase, while the Lagrangian track of the DDPM calculates the trajectory of each discrete sand particle as it moves through the water. The system considers forces like drag, gravity, and also the interaction with the channel walls, including the barriers which help to induce sedimentation. These multifactor interactions determine when and where the particles settle within the channel.

17. Kailey Kris

What impact do the diagonal barriers have on the sedimentation of sand particles in the simulation?

• MR CFD Support

The diagonal barriers in the channel create regions where the flow is disrupted and slowed down. This allows for the sand particles, which may have been suspended in the flow, to settle due to gravity, thereby aiding in the process of sedimentation. They essentially act as traps that increase the efficiency of sediment removal from the water flow.

20. Martine Marks

This training provided everything I needed to understand sedimentation! Just one question: how do the different diameters of sand particles affect the sedimentation rate?

• MR CFD Support

The different diameters of sand particles significantly impact sedimentation rates. Larger particles tend to settle more rapidly due to their greater mass, which causes a higher settling velocity. Conversely, smaller particles have slower settling velocities and may be carried further by the flow before they settle. The simulation includes varying particle sizes to accurately represent and predict this behavior in an urban sewer conduit context.

22. Vicente Macejkovic II

Does the structure of the obstacles inside the channel have a significant impact on sedimentation patterns?

• MR CFD Support

Yes, the structure of the obstacles inside the channel affects sedimentation patterns. These obstacles induce dead zones and flow separation, creating areas where the velocity decreases, and sedimentation is more likely to occur. The modeling thus considers these components crucial in understanding and predicting sedimentation phenomena.

23. Miller Skiles

I’m fascinated by the sediment simulation! Could you further explain the significance of the three rows of plates in the sedimentation process?

• MR CFD Support

Certainly! The three rows of plates, or diagonal barriers, in the channel are strategically designed to induce zones of lower flow velocity. This allows for the creation of favorable conditions for sand particles to settle out of suspension, thus aiding the sedimentation process. When the water and sand particle mixture encounters these barriers, the flow is disrupted, which can lead to the stagnation of water flow and reduced particle velocity. Consequently, this environment facilitates the settling of particles due to gravity, enhancing the efficiency of the sedimentation process within the conduit.

24. Ellie Bergnaum
