Description
Description
In this project, the transitional motion of a cube containing water and air is investigated by ANSYS Fluent software.
The fluid domain’s geometry is designed in Design Modeler, and the computational grid is generated using ANSYS Meshing. The mesh type is unstructured, and the element number is 168367.
Transitional Motion 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.
It is one of the most common multiphase flow investigation approaches due to computational cost convenience. The cube accelerates in the X direction with an acceleration equal to 5 m/s2, while gravitational acceleration in the -Y direction affects the multiphase entity.
Time solver is assumed unsteady.
Transitional Motion 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 position; further away from the cube’s front, pressure increases. We investigate the sloshing effect in a simple cube containing water and air, which is accelerating in the X direction considering gravity.
Pressure on the bottom of the cube increases as we move towards the back, and starting from 1290 Pa, gauge pressure reaches the high value of 6500 Pa at the back face of the cube.

Can the simulation model the effect of different cube motions?
MR CFD Support –
Absolutely! The cube’s motion is a parameter that can be adjusted in the simulation. This allows for a wide range of simulation scenarios, such as different amplitudes and frequencies of the cube’s motion.
Allen Blick –
Can the simulation predict the pressure distribution in the cube?
MR CFD Support –
Yes, the simulation can predict the pressure distribution in the cube. This is important for understanding the fluid dynamics and the forces on the cube’s wall.
Pasquale Ziemann –
The VOF method was used for capturing the water-air interface – did this lead to accurate representation of the sloshing effect?
MR CFD Support –
Thank you for your insightful comment! Yes, using the Volume of Fluid (VOF) method enabled us to capture the dynamic interface between the water and air with high accuracy, which is critical for correctly simulating the sloshing effect within the cube. The computational results closely follow the physical behavior of such two-phase flow scenarios. We’re happy to hear you’re engaged with the intricacies of this approach!
Lily Jacobson II –
I’m really fascinated by the transitional motion study. Can the results of this model be scaled to different container shapes or different fluids, or is the study specific to the cube geometry and water-air interaction?
MR CFD Support –
The methodology applied in this study, using the VOF multiphase approach and considering physics such as container acceleration and gravitational forces, is generally scalable to different container shapes and fluids. While the specific results may differ due to changes in geometry and fluid properties, the underlying principles remain the same, and the concept can be adapted to simulate a wide range of sloshing scenarios with different container shapes and fluid types. However, one should note that for each different scenario, an appropriate computational model should be developed considering the unique properties of fluids and geometries involved.

This training helped me understand fluid behaviors during transitional motion in a very practical way. The visualization of sloshing water and pressure distribution was highly detailed. What kind of applications can these types of simulations help with in the real world?
MR CFD Support –
Such types of fluid dynamics simulations are incredibly useful for analyzing the effects of sloshing in fuel tanks of vehicles like rockets and airplanes, liquid cargo in shipping containers, and the impact on stability in automotive fuel tanks during abrupt motions. These practical applications require precise modeling to ensure safety and efficiency, which sloshing simulations can provide.

Milo Daniel –
The project results are fascinating! I have always been interested in understanding how sloshing impacts container integrity. Could you provide more insight on the most significant factors affecting the stress distribution on the container walls?
MR CFD Support –
Of course! The stress distribution on the container walls in this sloshing simulation is mainly affected by the dynamics of the water movement and the pressure distribution. Factors such as the acceleration rate, the geometrical design of the container, the water volume, and the properties of the container’s material play a role in how stress is distributed during sloshing. The moving interface between water and air, along with the acceleration in horizontal force, the force of gravity, and the interaction between the two fluids, leads to a varied pressure distribution which is then translated into stress on the container walls.
