ResearchGranular Dynamics
Flowing granular materials often superficially resemble classical fluids, but due to their finite yield stress and effectively athermal particles, their dynamical behavior is often counter-intuitive and difficult to predict. Our primary research is this area focuses on segregation and mixing in multi-component particulate systems driven by flow kinematics and differences in particle properties like shape and size. Our research combines experiments, particle-level simulations, and models ranging from continuum transport to piecewise isometries, a recent branch of mathematics that can represent solids shuffling, to better understand and, consequently, control mixing in a wide range of natural and industrially relevant granular flows.
