Validation of macroscopic modelling of particle-laden turbulent flows

Abstract

Large-scale engineering sediment transport problems require advanced closures for the description of particle-turbulence interactions, in order to improve the predictive capacities of the numerical modelling tools, which are based on the continuous-phase approach. Recently developed closures have revealed new information on the suspension capacity of shear flows. Qualitative validation by comparison between model results and flume data confirm these new features and show the need for a more detailed modelling approach for the supersaturated near-bottom layer
