## Description

The present problem simulates the three-phase flow of water, air, and sand flowing over a circular weir using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

If any obstacle is placed on the path of the fluid flow, it causes the fluid level to rise behind it and increase its velocity, eventually leading to fluid overflowing on the obstacle. These obstacles are regarded as weirs. Weirs have different uses depending on their shape and are mostly used in civil engineering.

The present model is designed in two dimensions using the SpaceClaim. The meshing of the present project has been done using ANSYS Meshing software. The element number is 4,770.

## Circular Weir Methodology

In this project, the water will enter the computational domain with a velocity of 1m/s, and it flows over the sand bed behind the weir. The water flow will lift some of the sand and carry it as it flows over the weir.

The standard k-epsilon model is exploited to solve fluid flow equations, and the Eulerian multiphase model is used to investigate the motion and interaction of the existing phases.

## Circular Weir Conclusion

At the end of the solution process, two-dimensional contours related to the volume fraction of the air, water, and sand phases, pressure, streamlines, and velocity vectors are obtained.

As can be observed in the sand volume fraction contour, the water flow will lift some of the sand from its bed and move it as the water flows over the weir, now in the long term, the sand bed behind the weir will be washed completely, and the blank space behind the circular obstacle will turn into a tangential path for water.

4. Prof. Myrtis Denesik

The training for the circular weir simulation sounds fascinating. I noticed the chosen solver is k-epsilon. Could you detail why this specific turbulence model was selected over others for this simulation?

• MR CFD Support

The standard k-epsilon turbulence model was chosen for this simulation because it is known for its robustness and accuracy in predicting the average turbulence quantities, particularly for flows with high Reynolds numbers and in which turbulence is fully developed. In flows over weirs where the free surface is present and complex interaction between multiple phases occurs, the k-epsilon model provides a good balance between computational efficiency and the level of detail required for such multiphase flow simulations.

18. Dr. Pierre Dooley DVM

I was fascinated by how accurately the simulation showed the water picking up sand. Can you tell me more about how the multiphase modeling accounts for the interaction between the sand and water?

• MR CFD Support

The Eulerian multiphase model in ANSYS Fluent allows us to account for the interaction between the water and sand by treating each phase as a continuous interpenetrating medium. Momentum and continuity equations are solved for each phase and the interaction between phases is captured through interphase exchange coefficients. In this simulation, these coefficients manage how the sand is lifted and transported by the water flow as it goes over the weir. Additionally, the model accounts for the drag force that sand particles exert on the water flow and vice versa, which contributes to the simulation’s accuracy.

21. Ahmed Gaylord

I’m impressed by the Circular Weir Simulation! The attention to detail in modeling the three-phase flow is commendable. How effectively does the simulation capture the granular nature of the sand movement, and are additional computational concerns like erosion or deposition also accounted for in the training materials?

• MR CFD Support

Thank you for your kind words! The simulation captures the behavior of the sand with a high level of detail due to the use of the Eulerian multiphase model. This allows for the tracking of the volume fraction of each phase within the flow, giving a realistic representation of sand movement. Concerning computational considerations like erosion or deposition, these physical processes involve complex interactions and typically require additional modeling aspects such as defining erosion rates or tracking deposited layers over time. While the primary focus for the given simulation is on the three-phase flow interactions and initial lifting and transport of sand, long-term effects like erosion and deposition necessitate more advanced modeling strategies that might be included in more advanced training sessions.

22. Katelin Tillman Sr.

I’m amazed at how the simulation captures the water lifting the sand as it flows over the weir. It’s fascinating! Did the results also show how the design of the weir impacts the sand movement?

• MR CFD Support

Thank you for your positive feedback! Yes, the simulation results demonstrate how the shape of the weir significantly affects the movement of the sand. The circular design induces a specific pattern of water flow and turbulence that contributes to the lifting and transport of sand particles over the weir. Detailed analysis of this behavior helps in understanding and optimizing weir designs for effective sediment management in civil engineering projects.
