Multiphase Flows in Deformable Geomaterials: Chemo-Physical Coupled Mixture Theory and Non-Linear Thermodynamics

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. To address this gap, the book proposes chemo-physical Mixture-Coupling Theory and non-equilibrium thermodynamic processes to derive governing equations for multiphase transport and mechanical behavior. 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 and thermo osmosis and microscopic swelling mechanisms. It is written for advanced students and researchers.
