Description
Description
This simulation is about the Ogee spillway via ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The main task of this type of structure (spillway) is to remove excess water in situations such as a flood that water flow damages the dam body. The structure of these spillways consists of a vertical plate in the flow direction of the fluid, whose upper edge can be both sharp, curved, and wide.
Spillways have several types: open channel, chute, stepped, siphon, ogee, side channel, labyrinth, and so on. The purpose of the present study is to investigate the behavior of water flow after passing through an ogee spillway in the presence of airflow.
The geometry of the present model is drawn by Design Modeler software. The geometry of this model consists of a horizontal cylinder. It has a horizontal inlet for mixture flow and two vertical outlets for separated gas and liquid flows.
The model is then meshed by ANSYS Meshing software. The model mesh is unstructured, and 10959 cells have been created.
Ogee Spillway Method
Since the channel uses two different flows, the two-phase flow model is used. The two-phase VoF (volume of fluid) model is used in this simulation to define the water as the primary phase and the air as the secondary phase.
Since the phase separation boundary is completely distinct, the Volume of Fluid (VOF) model is used. The sharp type in interface modeling has been used to determine the behavior at the boundary between two phases.
Ogee Spillway Conclusion
After simulation, the contours of velocity, pressure, and mass fraction of water and air are obtained. The contours show that the water flow hits the dam body and starts to overflow from its upper edge. The excess water flow slides on the spillway slope and moves downwards with low pressure, preventing the flood from becoming stronger and more intense.

How does the simulation handle the interaction between the water and air?
MR CFD Support –
The simulation uses the Volume of Fluid (VOF) model to accurately capture the interaction between the water and air, including the formation of air bubbles and the behavior of the free surface.
Mrs. Bonita Leffler –
Can this simulation help in predicting erosion or structural damage in an actual spillway?
MR CFD Support –
While the simulation’s main focus is fluid dynamics, the results can provide insights into potential areas of high pressure or velocity that could lead to erosion or structural damage over time.

I’ve seen some impressive images of the water flow captured in these spillway simulations. How is the real_LOOK of water and air during overflow condition rendered in the results, especially considering the complexity of capturing the air-water interface?
MR CFD Support –
Graphical rendering of water and air in simulations like the ogee spillway is achieved through post-processing tools offered in ANSYS Fluent. Specifically, the VOF model along with interface capturing methods provides clear delineation of the phases. It yields realistic visualizations of water flow and air-water interface, highlighting areas of significant aeration and turbulence. Contour plots, pathlines, and vector fields illustrate the physics with high fidelity, and specialized rendering features and shaders contribute to the photorealistic appearance of the fluids.

Beaulah Gibson –
I’ve always been fascinated by the practical application of spillways. Could you please clarify how the VOF model ensures that the boundary between the air and water phases remains sharp during simulations?
MR CFD Support –
The VOF model assigns a volume fraction for each phase in every computational cell and reconstructs the interface between the different phases. In the simulation with a sharp type interface modeling, the reconstruction of the interface is ensured to be as sharp as possible by applying specific discretization and surface tension treatments, maintaining clear boundaries between distinct fluids like air and water.
Miss Ivory Gibson III –
Can this simulation be used for spillways of different shapes and sizes?
MR CFD Support –
The simulation setup can be adapted to study spillways of different shapes and sizes. The geometry and mesh can be modified to match the specific design of the spillway.
