A mathematical model for non-isothermal multiphase geomaterials which considers the dissolution of air in water and air mass sources during its desorption at lower water pressure is presented. The solid skeleton is elasto-plastic, isothermal or non-isothermal; heat, water and air flows and water phase changes are taken into account. Numerical solution of the model equations by means of the Finite Element Method for coupled problems is presented and a numerical example is shown.

Abstract
A mathematical model for non-isothermal multiphase geomaterials which considers the dissolution of air in water and air mass sources during its desorption at lower water pressure is presented. The solid skeleton is elasto-plastic, isothermal or non-isothermal; heat, water and air flows and water phase changes are taken into account. Numerical solution of the model equations by means of the Finite Element Method for coupled problems is presented and a numerical example is shown.File in questo prodotto:
