Overview: 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.
Details: Fellowship applications are due by December 4, 2020, and the project will start in Summer 2021. Fellows are appointed for a two-year term and will receive annual salary and benefits. At time of project start, applicants must have a PhD in one of the following or related fields: mechanical engineering, chemical engineering, material science and engineering. Must be interested in research in the field of suspension rheology. Must demonstrate excellent communication skills in the form of published papers and conference presentations. Some prior experience with rheology or computational modeling is required.
