Pore-Scale Modelling of Transport Phenomena in Drying

  • Chapter
Micro-Macro-interaction

Abstract

The work in this chapter is concerned with drying of capillary porous media and investigates how material properties characterizing the pore scale influence macroscopic process behaviour. A first approach to the problem takes a bundle-of-capillaries representation of pore space to parameterise a traditional continuous model of drying. In a second approach, the porous structure is represented by a network of pores, and transport is described by discrete rules at the pore level. By applying these two methods, the influence of pore structure, namely pore volume distribution and spatial correlations of pore size, is studied. Additionally, the role of individual transport phenomena, namely liquid viscosity and heat transfer, for drying behaviour is investigated.
