Direct Numerical Simulation of Locally Coupled Transport Processes at Dynamic Contact Lines


Subproject B02 is dedicated to the mathematical modeling and direct numerical simulation of dynamic wetting processes, in particular, in combination with interfacial transport processes. Methodologically, the Arbitrary-Lagrangian-Eulerian (ALE) method with moving computational grids is used. The explicit representation of the moving interface prevents numerical diffusion of the interface and also allows the discretization of partial differential equations for the modelling of transport processes along the interface. Thin boundary layers can be treated using subgrid-scale modeling. The method achieves high accuracy, but is limited with regard to strong deformations or topological changes of the interface. The aim is to further develop the models and numerical methods in order to achieve a predictive simulation of the dynamic wetting processes. We are investigating the dynamics of capillary rise (cooperation with A05 and B01 ), the dynamics of spreading droplets with A02 , the evaporation of mixtures during printing with C01 , and wetting under the influence of surfactants with A06 .
