This thesis is devoted to the modeling and numerical methods for the simulation of non-Newtonian flows, and focuses particularly on granular materials flows. This work is applied to molten powders aiming to ensure metal thermal protection from the air in ingot casting process of metallic alloys. These powders are conditionned into bags disposed into the mold, which burn due to high temperatures, and allowing the powder spreading onto the metal surface. Thus, numerical simulation appears as a powerful tool for the process optimization, and especially, for the powder spreading.In this work, a finite element formulation has been proposed for the modeling of granular multiphase flows, by a continuum approach. The associated equations are solve...
