Molecular Fluctuations Inhibit Intermittency in Compressible Turbulence
Ishan Srivastava, Andrew J. Nonaka, Weiqun Zhang +2
In the standard picture of fully-developed turbulence, highly intermittent hydrodynamic fields are nonlinearly coupled across scales, where local energy cascades from large scales…

An adaptive, data-driven multiscale approach for dense granular flows
B. Siddani, Weiqun Zhang, Andrew Nonaka +2
The accuracy of coarse-grained continuum models of dense granular flows is limited by the lack of high-fidelity closure models for granular rheology. One approach to addressing thi…
