Hierarchical Multi-Fidelity Learning for Predicting Three-Dimensional Flame Wrinkling and Turbulent Burning Velocity
Saghar Zolfaghari, Yu Xie, Junfeng Yang +1
High-fidelity experimental characterization of turbulent premixed flames remains limited by the cost and complexity of advanced diagnostics, particularly under elevated pressures a…

Non-local physics-informed neural networks for forward and inverse solutions of granular flows
Saghar Zolfaghari, Safa Jamali
Dense granular flows exhibit nonlocal effects due to stress transmission in microplastic events, especially in quasi-static or slowly sheared regions. Hence, traditional local rheo…

A Minimal Nonlocal Theory of Thixotropic Flow
Saghar Zolfaghari, Safa Jamali
Dense amorphous materials exhibit both nonlocal flow cooperativity and pronounced history dependence, yet existing continuum models capture only one of these features at a time. No…
