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
