Abstract

A network model for the time dependence of transport properties of porous materials is proposed. A statistical volume element (SVE) of a capillary pore network of porous materials is idealised by a discrete lattice model consisting of spheres and pipes representing pores and throats, respectively, which can be filled with either liquid water or gas. The time dependence of the transport properties is modelled by incrementally decreasing the radius of the water filled pipes and spheres accounting for the evolution of the microstructure. The microstructural model is applied to investigate the change of macroscopic transport properties due to microstructural changes.
