Research Structure

The priority programme 1506 investigates transport processes at fluidic interfaces on a continuum mechanical level, with increasing multi-physics phenomena at the interface including
  • Hydrodynamics of two-phase fluid systems
  • Transfer of mass and heat across deformable interfaces
  • Capillary and Marangoni effects
  • Effects of absorbed components (surfactants, colloids)
  • Phase change (evaporation, condensation)

The priority programme is anchored within Applied Mathematics, but with strong interdisciplinary links to the Natural and Engineering Sciences. The above-mentioned processes are studied using complementary approaches from the following research areas:

  • Mathematical modeling and analysis
  • Numerical methods and simulation
  • Experiments and Validation

Important goals of the Priority Programme are:

  • derive and expand mathematical models that describe relevant physico-chemical interface phenomena. Improve and deepen the understanding of mechanisms and phenomena occuring at fluidic interfaces by means of rigorous mathematical analysis of the underlying pde-systems.
  • development and analysis of numerical methods for the simulation of multiphase flow problems which resolve the local processes at the interface.
  • validation of the models and the numerical simulation methods by means of specifically designed experiments.

A guiding measure within the Priority Programme is the realization of a series of systematic Taylor-bubble experiments and the common usage of the obtained data for validation of mathematical models and numerical methods. The experiments are structured according to physical principles, starting from pure hydrodynamics via heat and mass transfer to variable surface tension effects and aim at providing local data. During the start-up phase of the Priority Programme, integral measurements from the group of A. Tomiyama (external fellow) are available to the members of the SPP 1506.
