CFD Flocculation Tank 3D Simulation Meeting Minutes

Fall 2008 Minutes

December 9, 2008

Accomplishments

• Set up and ran simulations with periodic boundary conditions at the walls along xy plane

Metric

• NA

Outcomes

• The shape and sizes of energy dissipation zpne were different from what was predicted in 2D model
• The energy dissipation zone predicted from 3D model with periodic boundary conditions was smaller with a higher maximum value, compared with the results from the 2D model

Issues

• The results from 3D periodic models were expected to be similar with the results from the 2D models
• Further simulation experiments were needed to invesigate the causes of the difference: vary the length of the period; use extremely small period length
