Internship | Flow induced forces in multiphase CO2 flow

Delft, Zuid-Holland 6 mois
Postuler maintenant

Improving the understanding of fluid-structure interaction of CO2 systems to design system support requirements

What will be your role?

To combat climate change the amount of CO2 released into the atmosphere must decrease rapidly. One of the ways to accomplish this is through CCS (Carbon Capture and Storage). In this process the carbon is captured at a source, transported though a system of pipelines and injected into the subsurface.

In these transport pipelines or in injection wells, multiphase flow can occur. This is because the phase boundary between liquid and gaseous CO2 is at conditions that can be found in these transport pipelines. The multiphase flow, in which the average density of the fluids can vary significantly, leads to forces acting on the pipelines, especially at bends. These forces can induce vibrations in the pipelines, which can cause wear and tear of the system. It is important to be able to estimate these forces and vibrations before the construction of a pipeline system.

Experiments have been performed with multiphase flow of CO2 in a pipeline with bends, in which the forces exerted by the multiphase flow on the bends in the pipeline have been measured. The goal of this project is to reproduce these experiments with CFD simulations. In the past, experiments with oil and air or oil and water could be reproduced with CFD. CO2 differs from these water/oil-air systems in that it has a much lower viscosity and surface tension. The challenge of this project will be to see whether these different fluid properties can be successfully incorporated into the CFD simulations and to determine to what extend the CFD is able to reproduce the experimental results within a reasonable calculation time.

MSc project (8-9 months). Must have followed fluid mechanics courses. Experience with CFD is a large plus.
