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
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
