Deciphering the flow-to-fracture transition in frictional fluids
Abstract
The goal of this proposal is to improve our fundamental understanding and predictive modeling capabilities in the emerging field of frictional fluid dynamics. To achieve this goal, we have proposed to develop a multi-scale modeling framework bridging the granular and the system scale. Per our accepted proposal, the major goals for the granular model during the first year of this project were: 1. Validation of our computational approach against experimental data, and 2. Incorporation of inter-particle friction. One modification we have made to our major goals for the granular-scale model is that we have decided to include compressibility in the gas phase as well. Initially, we were not sure whether this step is required given the relatively small scale of the experiments we want to reproduce, but a closer assessment of the experimental data has led us to the insight that compressibility effects are important. For the system-scale model our first-year goals were: 1. Evaluating appropriate representations of three-phase interactions, and 2. Extending the continuum model to the disaggregation limit.
