Simulation of Freezing and Thawing Processes with Capillary Effects in fluid filled porous media
First published: 03 December 2012
Abstract
In this contribution, a macroscopic quadruple model for the simulation of freezing and thawing processes in fluid filled porous media is presented. The main focus lies on the description of the distribution of fluid and ice pressure as well as solid deformation before, during and after the ice formation in consideration of energetic and capillary effects. Furthermore, the porosity change of the porous material is considered, i.e., the variation of permeability during ice formation will be simulated. The illustrated results of numerical examples will be presented to demonstrate the practical application of the model. (© 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
