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.
