Accurately capturing solidification of fluids and the development of residual stress is critical for fully predictive simulations for numerous applications in geoscience, nuclear safety, manufacturing, energy production, and bioscience. Researchers on this LDRD project developed, implemented, and demonstrated advanced constitutive models with yield stress to represent both fluid and solid behavior simultaneously. They also presented results from literature models and demonstrated the first finite element results for the Kamani Donley-Rogers model that was developed by Sandia Alliance partners at the University of Illinois at Urbana-Champaign (Illinois).
Predictions were compared to novel experimental results of gravitational settling of yield stress fluids in a Hele-Shaw cell. Both experiments and simulations showed solidification in regions of low applied stress near free surfaces and far from the inlet. These improved models for the birthing of residual stress will substantially improve predictions of Sandia’s encapsulation processes.
This project resulted in five publications consisting of one in Physical Review Letters in 2021, two in the Journal of Non-Newtonian Fluid Mechanics (1) (2), and the Physics of Fluids in 2022, and one in the Journal of Rheology in 2023. Additionally, this Sandia team had numerous collaborators from industry (3M, Proctor and Gamble), the government (U.S. Army Engineering R&D Center), and Sandia Alliance partners from Illinois, University of New Mexico, Georgia Tech, and the University of Utah.
