CFD Flocculation Tank Simulation Meeting Minutes
Fall 2008 Minutes
October 22, 2008
Accomplishments
- Verified the turbulence length scale of .004 and 10% turb intensity
- Wrote udf to determine the statistical distribution of G.
Completed runs for geometry of h=2b with baffle uniform spacing of [.13,.1, .07,.04].
Metrics
- Boundary layer thickness =.01. Turbulence length scale =.4*.01m=.004m
- Plot of velocity magnitude, and plot of turbulence dissipation
- Average G
Outcomes
- Baffle spacing for .04, ,07 runs "choked" the flow, and created large recirculating regions.
- Baffle spacing for .13 does not force enough up and down action in the fluid.
Issues
- The clearance height is too large, and we need to decrease this value to reduce the recirculating regions.
