Wetting simulation of the porous structure of a heat pipe using an eXtended Discontinuous Galerkin Method and a Parameterized Level-Set
Irina Shishkina, Matthias Rieckmann, Martin Oberlack +1
We perform high-order simulations of two-phase flows in capillaries, with and without evaporation. Since a sharp-interface model is used, singularities can arise at the three-phase…

Cell agglomeration strategy for cut cells in eXtended discontinuous Galerkin methods
Muhammed Toprak, Matthias Rieckmann, Florian Kummer
In this work, a cell agglomeration strategy for the cut cells arising in the extended discontinuous Galerkin (XDG) method is presented. Cut cells are a fundamental aspect of unfitt…
