Numerical simulation of freeze/thaw front propagation in a sample of porous media
Original language description
The freezing of water in porous media depends on various characteristics such as pore size, distribution of grains or boundary conditions. In this contribution we describe a numerical model of freeze/thaw process of a soil sample on the centimeter scale (laboratory sample of repacked sand with relatively low porosity and water) using the finite element method. The model is based on the Štefan problem with a modified latent heat release depending on the water content and is treated in axial symmetry the sample domain. We investigate the sensitivity of this model on initial conditions, material properties and boundary conditions. This contributes to a more profound understanding of freeze/thaw processes observed under laboratory conditions.
