Tracking Lagrangian transport in Lake Geneva: A 3D numerical modeling investigation

Causal mechanisms of the deep chlorophyll maximum in Lake Superior: A numerical modeling investigation

Investigation of Small Numerical Instabilities Generated by the Lagrangian Tracking Scheme

We have undertaken simulations of steady-state multiphase flows using the Lagrangian technique. It was noted that in previous studies, we found simulations for certain numerical parameters, flow conditions and problems, that it was not possible to achieve a high-order convergence for the residuals. In this paper we discuss some of these problems and attempt to solve them by various techniques. ...

A 3d Numerical Investigation of Fine Sediment Transport in an Oscillatory Channel

Recent findings on a diverse range of muddy seabed states revealed by 3D, turbulence-resolving simulations are first reviewed. These transitions have critical implications to offshore delivery of fine sediment in the ocean and wave dissipation. Assuming a small particle Stokes number, the Equilibrium approximation to the Eulerian two-phase flow equations is applied. The resulting simplified equ...

Field Measurements and 3D Numerical Modeling of Hydrodynamics in Chabahar Bay, Iran

As the first phase of a series of monitoring and modeling studies of Iranian coastal areas, Chabahar Bay, located on the north coast of the Gulf of Oman, was under a comprehensive monitoring and modeling study in 2006-2007. The study included an extensive one-year field measurements program to help understanding the ongoing processes in the bay and provide inputs or boundary conditions and vali...

A 3D Two-Phase Numerical Model for Sediment Transport

We have developed a three dimensional numerical model based on the two-phase equations to study the bed-load transport Chauchat and Médale (2009). We have considered two formulations of the model based on a two fluid or a single mixed-fluid description. The governing equations are discretized by a finite element method and a penalisation method is introduced to cope with the incompressibility c...
