“…Therefore, it is even more challenging for any attempt in deformation modelling. To the best of the authors' knowledge, only one theoretical formulation with numerical solution from Zou, et al [257] is available in the literature by far. Their work considered the dynamic capillarity effects in simulating transient two-phase flow in porous media.…”

“…Meanwhile, they also modelled the drainage-induced settlement (shrinkage) by expanding the pore-elastic consolidation theory [258][259][260] to embrace transient two-phase flow simulators. Table 6 describes the theoretical framework developed by Zou, Saad and Grondin [257]. For details of the derivation and assumptions of this theoretical framework, the work from Zou, Saad and Grondin [257] is worth following up on.…”

This work reviews the transient two-phase flow in porous media with engineering applications in Geotechnics. It initially overviews constitutive relationships, conventional theories, and experiments. Then, corresponding limitations are discussed according to conflicting observations and multiphase interfacial dynamics. Based on those findings, the dynamic nonequilibrium effects were so defined, which could also be abbreviated as dynamic/transient effects. Four advanced theories have already been developed to resolve these effects. This review collects them and discusses their pros and cons. In addition, this work further reviews the state-of-art in terms of experimental methods, influential factors in dynamic/transient effects, and modelling performance, as well as micromodel and numerical methods at pore-scale. Last, the corresponding geotechnical applications are reviewed, discussing their applicability in effective stress, shear strength, and deformation. Finally, the entire review is briefed to identify research gaps in Geotechnics.

The drying shrinkage of porous materials is significantly dependent on external relative humidity (). The perspective of temperature increase due to the climate change will accentuate the drying phenomenon in structures in lands and cities. The evolution of shrinkage can be determined by equivalent pore pressure consisting of capillary pressure , disjoining pressure and pressure caused by interfacial energy. For concrete structures, up to condition, standard models can reproduce the drying shrinkage experiments accurately. However, as the decreases to 30%, these models seem to be limited because the measured relationship () differs from the corresponding static equilibrium relationship as the drying occurs rapidly and the dynamic fluid flow effects on capillary pressure have been neglected. In this paper, the standard shrinkage model has been improved to take into account the dynamic flow effect and the viscoelastic behaviour of the solid skeleton. The dynamic and standard models have been compared with experimental results of drying shrinkage of concrete with two different relative humidity conditions. The standard model clearly showed its limitations at low external relative humidity . However, the dynamic model showed good prediction of mass loss and shrinkage strains at high and low humidity conditions. Furthermore, the numerical and experimental investigations indicate that not only the dynamic effects but also the additional pressure induced by surface energy should be taken into account to quantify the drying shrinkage of cement‐based materials at low condition.
