Abstract

Settling and consolidation of colloidal and non-colloidal suspensions are investigated from a nuclear Magnetic Resonance Imaging (MRI) vertical prototype. The mathematical model of Gibson with a 1D numerical modeling based on the Finite Element Method (FEM) are presented. A time ‘Lax Wendroff’ discretization with a shock capturing technique (Flux Corrected Transport, FCT) is used for the propagation of concentration fronts. Finally comparisons between experiment and simulation are proposed and discussed for the case of noncolloidal and colloidal suspension.
