Full Description

Multiphase Flows in Deformable Geomaterials proposes that multiscale coupling of multiphase flow and multicomponents within a deformable porous medium is complex and interdisciplinary and lacks a unified theory. Chemo-physical coupled mixture theory and non-linear thermodynamics processes can be used to derive multi-phase transport equations and mechanics. This addresses challenges in the existing multiscale coupling theory and brings together physics and chemistry within the realm of thermodynamics. The series of constitutive equations can be applied to any constitutive model in porous media, across many disciplines related to soils, concrete and catalysis.

This book is particularly addressed to geotechnical and geoenvironmental engineering - bringing together multiphase flows of water and gas, chemicals and within soils and rocks). Highlights include hydro-mechanical coupling, unsaturated hydro-mechanical-chemical coupling, thermo-hydro-mechanical coupling and thermo-hydromechanical-chemical coupling, with consideration of chemo-thermo osmosis and microscopic swelling mechanisms. It is written for advanced students and researchers.
