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

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.
