Macro-Scale Effects on Sub-Grid Closures in Gas-Solid Riser Flows
Macro-scale flow topology effects on sub-grid closure models in filtered two-fluid simulations of gas-solid riser flows.
Macro-Scale Effects on Sub-Grid Closures in Gas-Solid Riser Flows
Integrating a Three-Dimensional TKE-Based Subgrid Diffusion Scheme Into GFDL FV3
An inline 3D TKE-based subgrid diffusion scheme is embedded directly in the FV3 dynamical core, giving a unified turbulence treatment across the gray zone and large-eddy scales.

Macro-scale effects over filtered and residual stresses in gas-solid riser flows
Filtered and residual stresses of both phases depend strongly on the macro-scale state of the flow, so sub-grid stress closures cannot be built from meso-scale data alone.

On the effects of the flow macro-scale over meso-scale filtered parameters in gas-solid riser flows
Macro-scale flow topology parameters are shown to matter for sub-grid closure of filtered two-fluid models of gas-solid riser flows.
