CFD Flocculation Tank Simulation Meeting Minutes

Fall 2008 Minutes

November 6, 2008

Accomplishments

•  Completed the UDF for analyzing the distribution of the energy dissipation rate
• Changed the the top boundary condition of the flocculation tank to symmetry boundary and analyze the result

Metrics

•  UDF script was written
• Plot of the energy dissipation rate for symmetry boundary condition

 Outcomes

•  Symmetric boundary condition eliminated the high energy dissipation rate at the top wall

Issues

• Distribution plotted using UDF provides no insight into uniformity of energy dissipation rate
• Better method is needed for analyzing the distribution
• There is unknown problem about the Fluent compiler. It will give error even if the code is written correctly
