Abstract
Droplet impact dynamics is an example of a complex two-phase flow. However, we manage to reduce the complexity of this problem by reducing its dimensionality. This paper highlights an axisymmetric interface-capturing method [1, 2]. The level-set method is used for modeling the evolution of the front, because of its inherent ability to account for large topological changes of the interface [3], and is combined with a continuum surface force (CSF) model. We use a space-time finite element discretization, which is achieved by means of simplex space-time elements and leads to entirely unstructured grids with varying levels of refinement both in space and in time. Therefore, despite the complexity of the contact dynamics, the efficiency of our simulations is improved when using adaptive temporal refinement in areas of interest. Two different benchmark cases from [4] are used for verifying our numerical approach.KeywordsSpace-timeSimplexAxisymmetricTwo-phase flowsContact lines
