CFD Flocculation Tank 3D Simulation Meeting Minutes

Spring 2009 Minutes

March 6, 2009

Accomplishments

• Read the FLUENT documentation on parallel computing and remote executing
• Worked on finer mesh and boundary layers
• Literature research on energy dissipation map
• More simulations with 2D Reynolds Stress models
• Simulations comparing old 2D cases and report summaries of parameters setting

Metrics

NA

Outcomes

• Found out the reason caused the difference in the energy dissipation maps: the fluid material property was incorrectly set to air(default)

• Water does gives us longer energy dissipation region

• Lesson from the mistake: keep good documentations on the work that has been done, and organize the data, book keeping parameter settings

• This result should be further confirmed by: 3D modeling with k-epsilon realizable model, Reynolds Stress model

Issues

• There is still no observable speed scale-up with parallel computing
• Need to study FLUENT documentation to get more familiar with Linux and parallel computing and figure out the right commands to use
