Description
Description
The present problem simulates the siphon phenomenon using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
Water always flows from an area under higher pressure to an area of lower pressure. The siphon effect occurs when the fluid flows to the highest portion of the bend pipe due to the pressure difference and then comes down from there due to gravity.
The present model is designed in two dimensions using the SpaceClaim software. The meshing of the model was done using ANSYS Meshing software. The element number is 95451.
Also, due to the nature of the problem, the transient solver is enabled.
Siphon Methodology
This project uses the VOF multiphase model to simulate and solve the two-phase flow field equations. The flash tank discharges and the siphoning effect causes the water to drain.
The K-epsilon Realizable viscous model with scalable wall function has been used to solve the turbulent flow equations. The pressure-velocity coupling scheme is SIMPLE.
The second-order upwind discretization method has been used for Momentum, and the first-order upwind discretization method has been used for Turbulent kinetic energy and Turbulent dissipation rate.
Initially, the patching option was used to add the water phase into the domain.
Siphon Conclusion
After the solution process is completed, contours of velocity, pressure, water volume fraction, and streamline are extracted and presented below. As observed, the water inside the flash tank discharges and causes the siphoning effect.
Due to the siphoning effect, water will pass through the pipe and go to the highest point, and then due to gravity, it will come downward. Once the water flow has begun, the water will continue to flow, draining the ponding area.

I’m amazed by the detail in the simulation reports! Could you let me know whether changes in ambient temperature were considered in the model as well?
MR CFD Support –
In the siphon CFD simulation project using ANSYS Fluent software, ambient temperature changes generally wouldn’t be taken into account if the main focus is on fluid mechanics and the siphon effect. Typically, the results presented in the report are focused on velocity, pressure, water volume fraction, and streamline, which are the primary factors demonstrating the siphoning phenomenon.

Prof. Devan Hackett V –
I’m intrigued by the siphon effect simulation. How does the VOF multiphase model ensure accurate representation of the water and air phases throughout the simulation? Can you explain that in simpler terms?
MR CFD Support –
In this simulation, the VOF (Volume of Fluid) multiphase model is used to keep track of and locate the free surface boundary between the water and air phases accurately. The model allows us to follow and predict the shape of the liquid-free surface – in this case, the water – as it rises to the highest point of the siphon and drains due to gravity. Simple terms, it’s like combining both liquid and air in the same container but being able to tell precisely where each starts and the other ends at any point in time.

Nora Sawayn –
I’ve always been amazed by the siphon phenomenon. Could you tell me if any specific boundary conditions were used to emulate the gravity effect in the simulation accurately, or if it’s automatically accounted for in ANSYS Fluent?
MR CFD Support –
Gravity is inherently considered in ANSYS Fluent simulations; it plays a critical role in siphon phenomena where fluid dynamics are influenced significantly by gravity. In the setup of this simulation, the gravity vector would be defined to ensure an accurate representation of the siphonic action. The traditional definition of gravity within Fluent effectively simulates the flow of water from a higher to a lower elevation, enabling the proper functioning of the siphon.
Devante Kassulke –
What steps did you follow to ensure the siphon effect was accurately captured in the simulation?
MR CFD Support –
In order to accurately capture the siphon effect in the simulation, we first designed a two-dimensional representation of the siphon setup using the SpaceClaim software. The meshing was meticulously created with ANSYS Meshing software to capture the nuances of the flow, especially around the bend of the siphon. Using the VOF multiphase model, we captured the interface between water and air. The use of the K-epsilon Realizable model helped to accurately model the turbulence effects. Patching was essential to define the initial water phase in the domain. Boundary conditions were applied rigorously, accounting for pressure differences that drive the siphon effect. The application of SIMPLE scheme allowed for steady pressure-velocity coupling, and various discretization methods calibrated to capture velocity and turbulence effectively.

Scottie Mann DVM –
How does the software ensure continuity in the water flow once the siphoning effect takes place? Will it maintain the flow without interruption?
MR CFD Support –
In the simulation, the continuity of the water flow once the siphoning effect initiates is maintained through the proper handling of boundary conditions and the use of the VOF multiphase model, coupled with necessary turbulence and pressure solvers. As the siphon effect relies on gravity and pressure differential, as long as the simulated conditions don’t change, ANSYS Fluent will consistently solve the flow equations in each time step, allowing the water to continue flowing without interruption.

Mrs. Karine Grady –
What is the reason for using the SIMPLE pressure-velocity coupling scheme in this simulation?
MR CFD Support –
The SIMPLE (Semi-Implicit Method for Pressure Linked Equations) pressure-velocity coupling scheme was chosen in this simulation due to its robustness and efficiency when solving the incompressible flow equations present in siphon dynamics. It provides a reliable method of intertwining the calculations of pressure and velocity fields, which is crucial for simulating the siphon effect accurately.
