To model submarine flows of granular materials we propose an extension of the drift-flux
approach. The extended model is able to represent dilute suspensions as well as dense …

Intense transport of bed load is associated with highconcentrated sediment-laden flow over
a plane mobile bed at high bed shear. Typically, the flow exhibits a layered internal structure …

By the late nineteenth century, the scientific study of bedload transport had emerged as an
offshoot of hydraulics and geomorphology. Since then, computing bedload transport rates …

Granular flows are ubiquitous in nature with single flows traversing a wide range of dynamic
conditions from initiation to deposition. Basal forces exerted by environmental granular flows …

In this chapter, the equations governing the dynamics of particulate flows are presented and
discussed. We focus here on the notion of 'particle resolution scale', in terms of whether …

To permit the tracking of turbulent flow structures in an Eulerian frame from single‐point
measurements, we make use of a generalization of conventional two‐dimensional quadrant …

The local granular phase rheology in bedload transport is investigated from discrete
numerical simulations. The numerical model is based on a coupled Discrete Element …

This paper outlines the various approaches used to calculate bedload transport. As bedload
transport exhibits considerable spatial and temporal variations, computing the bedload …

We present a collision model for phase-resolved Direct Numerical Simulations of sediment
transport that couple the fluid and particles by the Immersed Boundary Method. Typically, a …
