Project Description
Controlling the flow of concentrated particle suspensions is crucial in a plethora of applications such as the creation of biomass slurries for renewable fuels, metal pastes in solar cells, thermal interface materials, solid oxide fuel cells, and additive manufacturing/3D printing. These concentrated suspensions are made up of spheres or particles with anisotropic shapes (rods, fibers, platelets) and often operate close to the jamming fraction. Developing models and measurement tools to understand and predict the flow behavior of concentrated particle suspensions is crucial to optimize many industrial processes. This project uses a combination of rheological experiments and computational models to investigate the fundamental flow behavior of concentrated suspensions. The goal is to quantify rheological properties of the suspension including yield stress, normal stresses, and relative viscosity of the concentrated suspension under different conditions.
