3D porous media liquid-solid interaction simulation using SPH modeling and Tomographic images

We propose to study the mechanical properties of a volcanic soil sample (monolith) using a computer model. We propose the use of CT-images to construct the Mechanical Computational Model. The image obtained from the CT-Scan give us a 3D model of the pores system of the monolith. This system relates the internal connectivity between different pores and the soil volume. To simulate fluid-solid interaction and the mechanical properties of the soil monolith model we used Smoothed Particle Hydrodynamics. This method has a proven track report to solve multistate interaction. As SPH relies on a set of points without using a Tetrahedral Mesh representation, we can relate easily the intensity value of each pixel of the CT-Scan images (related to density values) to our 3D point data set. We aim to our 3D pore network model and the SPH evolution modelling technique to simulate the fate of solutes in porous media. Such study is of importance to the soil sciences community to accurately predict the impact of pollutants and chemical compounds in groundwater supplies.
