CFD Flocculation Tank 3D Simulation Meeting Minutes

Spring 2009 Minutes

April 17, 2009

Accomplishments

• Ran simulation for 5 turnings: h/b =2,5,10,15
• Calculated performance parameters with modified UDF

Metrics

NA

Outcomes

• Change of material from air to water has a great effect on the shape and size of the energy dissipation region

Issues

• Predicted energy dissipation pattern was not consitent with what was hypothesized. Need to:
• Change the boundary condition at the top of the flocculator to investigate the effect of no-slip boundary condition define at the water surface
• Check the sensitivity of performance parameters to Reynolds number
