Simulation model for 2 phase pipe flow

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
DeLaval is world leader in milking equipment in the dairy industry. The process of cleaning the milking installation is done with a combination of chemicals in contact with all equipment and physical treatment of the surfaces by a cleaning solution. The physical treatment is done by an intermittent air injection to the pipeline when a sufficient amount of cleaning solution is present. A slug/plug is created that travels through the pipeline.
In order to be able to improve the configuration of the cleaning program on farm there is a need of a theoretical model to be able to simulate the water and air flow. The model will be used in optimization of pipe layout and water usage to ensure an effective and rational cleaning that is easy for installer to set up.
The project will include fluid dynamics, surface chemistry and visualization of the results with main focus on creation and sustaining the slug throughout the pipeline. The final project directive will be discussed with the student and the tutor at University to match the applicant.
