Description
Description
In this project, the rotation of a cube containing water and air is investigated by ANSYS Fluent software. The cube rotates around the Y-axis with variable angular velocity. The cube’s distance to the rotation axis is equal to 1 m.
The angular velocity of rotation varies with time as the function 0.252273*sin(2.53*time+36800).
The fluid domain geometry is designed in the Design Modeler, and the computational grid is generated using Ansys Meshing. The mesh type is unstructured, and the element number is 168367.
Cube Methodology
The interaction of water and air inside the cube is modeled using the Volume of Fluid (VOF) multiphase approach. VOF multiphase approach is considered since it is an efficient and precise approach for capturing the interface location between phases.
A User Defined Function (UDF) defines the variable angular velocity of the cube’s rotation. Also, the solver is Transient.
Cube Conclusion
This project investigates the simplified sloshing effect in fluid containers where a situation similar to the one studied here can occur due to the acceleration of the carrier vehicle.
Results show that pressure on the bottom surface of the cube varies with radial distance to the OO line. Pressure increases as the position are away from the OO’s line.

The results you’ve reported are fascinating! It really shows the complexities of sloshing effects captured through simulation. Did the training cover the analysis of how these pressure variations can impact the structural integrity of the cube or on the forces experienced on its walls?
MR CFD Support –
We are thrilled to hear you valued the insights from our training! The primary focus of the training session revolves around sloshing dynamics within a rotating cube and its impact on internal pressure distribution. While the fundamental training emphasizes fluid behaviors and pressures, a comprehensive engineering analysis may entail additional considerations of the forces and their implications on the structure, which can be advanced topics for additional study or later modules.

Alexandrea Bradtke –
The results mention pressure changes in relation to the distance from the OO line. Does this mean that pressure distribution changes uniformly across the cube’s bottom or there are specific patterns formed due to the rotation?
MR CFD Support –
The pressure distribution on the bottom of the cube does not change uniformly due to the rotation. Due to the centrifugal forces in action, pressure is expected to be higher at points further away from the axis of rotation (OO line). Specific patterns can form as a result of the sloshing dynamics, which depend on the interaction between the rotating motion and the fluid’s response to it.

The project looks intriguing! Was the transient solver setup challenging given the variable angular velocity, and did you face any convergence issues during the simulation?
MR CFD Support –
Thank you for the kind words about our project! Setting up the transient solver with the variable angular velocity, defined by a User Defined Function (UDF), was indeed a meticulous task, but it was essential for accurately simulating the cube’s dynamics. While transient simulations can pose convergence challenges, particularly when dealing with moving boundaries and multiphase flows such as sloshing, careful setup and tuning of the solver parameters helped in achieving stability and convergence of the results.
Deborah Armstrong –
Is the variable angular velocity implemented in the model critical for accurately simulating the sloshing phenomenon?
MR CFD Support –
Yes, the variable angular velocity is crucial for simulating the sloshing phenomenon as it recreates the dynamic environment that is usually responsible for sloshing in real systems. By utilising a UDF to replicate this varying motion, simulations can mimic the actual conditions leading to sloshing, providing insights into how fluid behavior changes over time with changing velocities.
Herbert O’Reilly –
Are there any visual aids provided like animations or graphs, so I can better understand the sloshing effect inside the cube throughout the simulation?
MR CFD Support –
Animations and graphical representations are valuable tools to visualize and understand the sloshing effect in a rotating cube simulation. These can help better grasp how the liquid motion within the cube responds to changes in angular velocity over time.
Dr. Stephen Hyatt –
The dynamically varying angular velocity seems complex. Does the provided User Defined Function (UDF) account for appropriate changes during the simulation?
MR CFD Support –
Yes, the User Defined Function (UDF) is specifically scripted to manage the time-dependent angular velocity that changes as a sine function of time, ensuring that the variable angular velocity is accurately represented throughout the transient simulation.
