Fluids and Porpous Material

Jump to: Research Aim | Research Methodologie


The rich pallet of interactions ae studied from nano- to macroscale and from very short to long time scales.
We focus on:

  • fluid (gas and /or liquid) transport at different pore scales and its coupling to heat transport.
  • phase change between liquid and gas at molecular, pore and macro- scales, including heat exchange.
  • coupled mechanical-sorption hysteresis behaviour, including swelling-shrinkage.
  • surface phenomena such as droplet impact on porous substrates, film forming and run-off.

More applied research covers applications such as convective drying, hygrothermal behaviour of building components, leaching of biocides.

Methods and Approach

Our scientific approach is based on the coupling of advanced experimental and computational methods. Advanced imaging is used to document the fluid-porous interactions in the material at different scales, providing essential insights in the undertanding of the phenomena at play. Theorethical and computational modeling provides the capability to determine material properties from experiments using inverse identification, to design optimal experiments and to explore new pathways for material development and technology innovation.
