Title: "Investigation of Energetic Granular Flows via Simulations, Experiments and Theory"
Abstract:
Nearly every product or commodity in use is constituted and/or derived from granular materials through mining, agriculture, and/or chemical processing. Consequently, industries involved with the handling and processing of bulk solids contribute substantially to the global economy. The development of predictive paradigms capable of spanning granular flow regimes (i.e., quasi- static to energetic) prevalent in industrial systems poses a formidable scientific challenge due to the enormous complexity of phenomena occurring over widely different time and length scales. In this presentation, we discuss a synergistic methodology that couples discrete simulations, physical experiments and theoretical modeling, with the goal of identifying key parameters, quantities and features of the dynamics that govern flow behavior. The approach is demonstrated via a seemingly simple system consisting of a column of inelastic spheres, subjected to taps in the form of half sine-wave pulses, in which the interplay between diverse time and length scales are central contributors to the column’s evolving dynamics.
