In large-eddy simulation (LES) of turbulent dispersed flows, modelling and numerical
inaccuracies are incurred because LES provides only an approximation of the filtered …

Sediment transport is studied as a function of the grain to fluid density ratio using two phase
numerical simulations based on a discrete element method for particles coupled to a …

A subgrid scale particle kinetic turbulent energy model coupled with a second order moment
model is developed to describe the particle hydrodynamic characteristics in dense gas …

A prominent control on the flow over subaqueous dunes is the slope of the downstream
leeside. While previous work has focused on steep (~ 30°), asymmetric dunes with …

This paper presents a large eddy simulation (LES) of turbulent open channel flow over two-
dimensional periodic dunes. The Reynolds number R based on the bulk velocity U (bulk) …

The transport of dense particles by a turbulent flow depends on two dimensionless numbers.
Depending on the ratio of the shear velocity of the flow to the settling velocity of the particles …

A novelty particle subgrid scale model is established to model the effect of gas flow on
particle motion behaviors and a four-way coupling method to describe the particle-particle …

Flow structures of non-swirling and swirling particle-laden turbulence are modeled using the
large eddy simulation. Four-way coupling to reveal the interaction mechanism of gas to …

Subgrid-scale (SGS) gas flow and particle-particle collision are closely related to the particle
dispersions in swirling gas-particle flow. However, investigations which consider the four …

A CFD-based multiphase method for the numerical modeling and simulation of particulate
fouling of structured heat transfer surfaces is presented and validated using different …
