IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Euler-Lagrangian LES Study of Two-phase Sediment Cloud Dynamics Related to Open-water Disposal
Author : Ruo-Qian Wang
This article uses four-way coupling Euler-Lagrangian Large-Eddy Simulations to resolve particle cloud dynamics. The fractioned Navier-Stokes equations are numerically solved for fluid phase motion, solid phase motion is addressed by Lagrangian tracking for every single particle, and total momentum is conserved by fluid-solid inter-phase coupling. We validate the code by comparing numerical results with experiments in terms of particle cloud settlement and growth. A good comparison is obtained showing the reliability of the present numerical schemes. The time and height of phase separations are defined and analyzed for a variety of initial release conditions. Empirical formulas are drawn to fit the results.At last, an example is given to show how tooptimize an open-water disposal project using the newly obtained principles.
