Matthäus Jäger examines the simulation of liquid-gas flow in fuel tank systems and its
application to sloshing problems. The author focuses at first on the physical model and the
assumptions necessary to derive the respective partial differential equations. The second step
involves the cell-centered finite volume method and its application to fluid dynamic problems
with free surfaces using a volume of fluid approach. Finally the application of the method for
different use cases is presented followed by an introduction to the methodology for the
interpretation of the results achieved.
