Priority Programme 1506 "Transport Processes at Fluidic Interfaces"

The Senate of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has announced the establishment of a new Priority Programme, entitled "Transport Processes at Fluidic Interfaces". The programme is designed to run for six years.

In multiphase flow systems there are several physico-chemical processes that determine the systems' behaviour, e.g., the fluid dynamics in the different fluids and the dynamics of the interfaces, heat and mass-transport between the fluids, adsorption effects at the interface and transport of species on the interface, variable interface properties, phase changes. In general these processes are strongly coupled and properties of the interface play a crucial role. A rigorous understanding of the behaviour of such very complex flow problems must be based on physically sound mathematical models accounting especially for local processes at the interface.

The aim of this Priority Programme is to further develop and expand such models, to analyse their mathematical properties and to develop and advance numerical methods for the rigorous simulation of these models. The realisation of this requires interdisciplinary research with expertise from applied analysis, numerical mathematics, interface physics and chemistry as well as relevant research areas in the engineering sciences. Important goals of the Priority Programme are:

  • derive and expand physically sound 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 long-term vision is that the validated models and simulation tools developed in the Priority Programme induce significant advances in future high-tech applications in, for example, lab-on-a-chip systems, multiphase reactors in chemical engineering and micro process engineering.

As a special measure to promote the validation by means of experimental data, a couple of research projects on Taylor bubbles in mini-channels shall be funded. More details concerning this experimental part can be found on the programme's website.

Tandem projects that address topics from more than one of these areas, for example numerical simulation combined with experiments (not necessarily on Taylor bubbles), in a coordinated research plan are welcome.

To keep the focus of this programme sufficiently narrow and foster synergies between participants, research solely related to the following topics will not be part of the programme:

  • interactions with solid interfaces or walls
  • multiphase systems in which interfaces and their local properties are not explicitly modelled
  • multiphase systems in which interfaces are only considered as geometric boundaries without physical properties
  • models for multiphase flow problems that are not based on continuum mechanics principles

Colleagues from neighbouring countries who are interested to participate in the activities of this Priority Programme should contact one of the two scientific coordinators of the programme.

Proposals for an initial three-year funding period should be submitted in English language by 7 September 2009 marked with the reference code "SPP 1506" to Deutsche Forschungsgemeinschaft, Fachreferat Mathematik, Kennedyallee 40, 53175 Bonn.

One paper copy (signed by all principal investigators (PIs) of the corresponding proposal) will be needed that contains as enclosures the scientific CVs of the applicants, of possible or intended scientific coworkers (if already available; especially in the case of postdoctoral researchers) as well as their (complete) publication lists (last five years). From the work programme within the proposal it should become clear which parts are assigned to which scientific coworker, especially which tasks should be fulfilled by PhD students or postdocs. In the case of joint proposals the assignment of requested funds to the individual PIs should also become clear. Next to a maximal 15 lines long and formula-free summary (for DFG's general decision board) a table providing an overview of the requested funding is requested. Furthermore, an electronic version of the proposal and of all the relevant enclosures should be enclosed in pdf-format also on a CD. On this CD selected and relevant publications may also be added.
