Geologic CO2 sequestration is considered to be the most promising technique to reduce the concentration of greenhouse gases in the atmosphere. Among all the storage options, deep saline aquifers have the greatest potential and due to their worldwide occurr ...
An understanding of the mechanics of unsaturated geomaterials has become an important component of the background of a geo-engineer operating in various fields of geomechanics. Several geotechnical operations, such as compaction and excavation processes, a ...
The pores in cementitious materials, their sizes and connectivity have an important influence on the durability of concrete. Several microstructural models have been developed to simulate the three-dimensional pore network in cement pastes. In this article ...
This thesis is about the simulation of flow, transport and geochemical reactions in variably saturated soils. Motivated by the problematic disposal and revegetation of residue from aluminium refining, novel modelling tools for general geochemical reactions ...
This paper aims to identify and evaluate various critical mechanisms associated with the processes of desiccation shrinkage in drying silty soils. A previously developed 1D bundle-of-tubes model is refined to simulate the various stages of drying shrinkage ...
The selective radius shift model was used to relate changes in mineral volume due to precipitation/dissolution reactions to changes in hydraulic properties affecting flow in porous media. The model accounts for (i) precipitation/dissolution taking place on ...
In this paper we propose a novel theoretical model for the dielectric response of variably saturated porous media. A model is constructed for fully saturated porous media as a combination of the well established Hashin and Shtrikman [1962] bounds and Archi ...
Microcellular aluminium can be produced by replication in porous material with pores across a wide range of sizes but with otherwise identical structures. Compressive tests reveal a plasticity size effect, with samples showing higher strengths and higher r ...
Based on the one-dimensional Biot consolidation equations, this paper developed an advection-diffusion equation that incorporates saturation, compressibility of the pore fluid and longitudinal dispersivity of the solute transport in an unsaturated, deformi ...
Classical Darcy's law assumes that the intrinsic permeability of porous media is only dependent on the micro-geometrical and structural properties of the inner geometry of the medium. There are, however, numerous experimental evidences that intrinsic perme ...
