A Thermodynamic Model of Compressible Porous Materials with the Balance Equation of Porosity

  • Krzysztof Wilmanski
Article

Abstract

The paper is devoted to the construction of a thermodynamic continuous model of porous media with changing porosity. It is shown that these changes are described by a balance equation. The flux in this equation is connected with a relative motion of components and the source describes a spontaneous relaxation of microstructure. Deformations of the skeleton can be arbitrary and a consistent Lagrangian description of motion of all components is applied.
