Pore Network Modelling in Process Engineering
In pore network modeling, the porous medium is represented by a network of geometrically similar pores, and transport phenomena are modeled directly at the pore scale. This discrete approach allows for the simulation of relatively large porous structures taking into account most of its microscopic properties. In the past, we have developed pore network models to study the role of various transport phenomena, e.g. friction or heat transfer, as well as the influence of the pore structure on the drying and wetting behavior of porous media.



 
The major current research goals of my group are:
  • finding effective transport parameters for use in continuous drying models from representative pore networks
  • drying experiments with micromodels to validate pore network simulations
  • validation of pore network modeling by drying experiments with X-ray micro-tomography
  • modeling of salt crystallization within a porous matrix during drying
  • modeling and measurement of fluid transport in loop heat pipes
  • modeling and measurement of fluid transport in the gas diffusion layer of a fuel cell during gas purge
In this way, the discrete method of pore network modeling can link pore scale and process scale – either directly or as a tool in a multiscale approach, taking input from a discrete microscopic model and feeding a continuous model at the macro-scale with parameters. Pore networks account only for phenomena in the void space, but they may be complemented by other methods (e.g. discrete element method) for a holistic description of processes. Real pore structures are represented by pore networks in a more or less adequate way: therefore, methods to assess the adequacy of a network representation as well as alternative modeling tools are being developed. Pore network models are extended to industrial porous materials and shall be used as a design tool to improve the performance of materials such as composites, catalysts, ceramics, etc.
