Description
Description
This project is related to the numerical simulation of the Wall with Wavy Motion using ANSYS Fluent software. We aim to consider the effect of a non-stationary wall on the water flow. We assumed that water flows in a two-dimensional channel. We considered that the bottom wall of the channel has wave motion.
This product is the sixth chapter of the Dynamic Mesh Training Course.
In this project, we simulated the water flow inside a channel with wave motion. We aim to model the wavy motion of the bottom wall of the channel. The wavy motion of the wall changes the behavior of the fluid in the channel. So, the mesh of the computing domain deforms over time.
We modeled the geometry of the project using Design Modeler software. The geometry is related to a channel with a non-stationary wall. The computational domain includes the internal space of the channel. Then we meshed the model with ANSYS Meshing software. The model mesh is unstructured, and the number of cells equals 146,998.
Wavy Motion Methodology
The Dynamic Mesh Model is used in this simulation. We generally use a dynamic mesh whenever we have a moving boundary or a deforming zone.
Here, a wall creates a wave motion. So this causes the mesh to deform over time. Therefore, we define a user-defined function (UDF) to define the wavy motion of the wall. To apply the wave motion to the wall, we must use the Grid Motion UDF.
According to the wavy motion of the wall, the mesh zone above the non-stationary wall is deformed. So, for this zone, we use the Deforming option.
Due to the nature of this modeling, fluid behavior is time-dependent. Hence, we use the unsteady (Transient) solver.
Conclusion
After the solution, we obtained pressure and velocity contours. Because the wall moves over time, we obtained the velocity and pressure contours animation.
The results show that the pressure and velocity are constantly changing under the influence of the wave motion of the channel wall. The wave motion causes the cross-section of the flow to change along the channel. As the cross-section decreases, the velocity increases, and the pressure decreases. If the cross-section increases, the velocity decreases, and the pressure increases.

Jo Beer –
The UDF you mentioned for the wave motion of the wall, could you explain how exactly it defines the wavy motion?
MR CFD Support –
Certainly! The UDF, or User-Defined Function, is a customized script written in C programming language that defines how the wall’s motion changes over time. This script calculates the motion of the wall at each time step, ensuring that the wave motion is accurately represented in the simulation. The wavy motion is typically defined mathematically by sine or cosine functions wherein the parameters like amplitude, frequency, and phase shift determine the characteristics of the wave motion. The UDF dictates these values to Fluent, which then dynamically adjusts the mesh to adapt to this motion throughout the simulation.

Christophe Weissnat –
The dynamic wavy motion simulation results sound fascinating. What kind of patterns did you observe in pressure and velocity fields over multiple cycles of wave motion? Were there any periodic or changing trends over time?
MR CFD Support –
Thank you for your interest! The excitation of wavy motion on a wall within a channel indeed presents intriguing fluid dynamics characteristics. As per the simulation outcomes, the pressure and velocity fields demonstrated noticeable fluctuations correlating to the wavy wall motion. These fields responded variably as the wave peaks and troughs moved along the channel. Specifically, with the wall elevating to form a peak, the channel’s cross-sectional area available for flow shrank, leading to augmented velocity and diminished pressure in that segment. Conversely, as the wall dipped creating a trough, the cross-sectional area expanded, causing the fluid’s velocity to diminish and its pressure to expand. These reciprocating alterations forged a periodic pattern in the channel, creating a complex interplay of fluid forces directly linked to the wall motion.
Benjamin Jenkins II –
I’m fascinated by the concept of dynamic mesh and the wavy motion of the wall. Can you please explain how the use of Grid Motion UDF improved the simulation outcomes for this project?
MR CFD Support –
In this simulation, the Grid Motion UDF (User-Defined Function) was fundamental to accurately model the non-stationary wavy motion of the bottom wall in the channel. By incorporating the UDF, we define the exact motion and deformation that occurs on the wall over time. This approach enhances the realism of the simulation by allowing the mesh to adapt dynamically to reflect the changing geometry. As a result, it ensures that the fluid dynamic calculations account for the wall’s movement, providing more accurate representations of pressure and velocity changes within the water flow.
