Title: CFD modeling and simulation of ballast water exchange

Speaker: Dr. David Reid, NOAA Great Lakes Environmental Research Laboratory

Date: Thursday, December 7

Time: 2 PM

Location: NOAA/ GLERL
             2205 Commonwealth Blvd., Ann Arbor, MI, 48105

Abstract:
Computational fluid dynamics (CFD) methods were used to model the flow 
behavior inside a ballast tank from a 35,000 dwt Great Lakes bulk 
carrier during flow-through ballast water exchange (BWE), and to 
investigate the use of CFD to predict and analyze BWE effectiveness. A 
CFD model based on a commercial viscous flow solver, Fluent (Fluent, 
Inc.) was applied to the ballast tank architecture from a Great Lakes 
bulk carrier. First, a 1/3-scale physical model of a portion of the 
ballast tank was built and used for validation experiments using Laser 
Induced Fluorescent techniques. The CFD model predictions are compared 
to the physical model experimental data obtained for three different 
conditions (ballast and exchange water densities and exchange flow 
rates). Based on the results to date, the CFD model predictions compare 
favorably with the experimental data but would not be sufficient for 
regulatory use related to ballast exchange efficiency analyses. An 
uncertainty analysis needs to be performed to determine confidence 
limits for the experimental data. The way the CFD model handles mixing 
needs to be evaluated and possibly modified, as does the grid structure. 
A CFD model-based simulation of a three-volume ballast water exchange in 
the full scale tank will be presented in computer animation format.
