2D Sloshing simulation in a round tank oscillating from left to right. The simulation was done with the CFD code Trixi.jl [1] which was extended with a three-equations model [2]. The model consists of a two-phase flow simplification of the Baer–Nunziato equations of compressible multi-phase flows [3]. The shown simulation is part of combined research efforts of the German Aerospace Center (DLR) and the University of Cologne to create computational models of sloshing dynamics in liquid hydrogen storage systems on mobile platforms such as cars, ships, and planes.
