Spring 2009 Goals

1. Validation of CFD models in terms of energy dissipation map: compare different turbulence models and with experimental data

1. • Further work with 3D rke
     • Solve the puzzle of different prediction from 2D and periodic 3D models
     • Finer mesh
     • Run simulation on SGI servers

1. Data analysis, interpretation, geometry variation and design recommendation

• Appropriate mesh in 3D
  • Mesh interval size and boundary layers
  • Validate: Check grid convergence, etc.
• Define the model in FLUENT
  • Turbulence model and other parameters
• Validation of the model
  • Numerical stability: convergence, accuracy
  • Compare with experimental data: find similar flows and related experimental data (free/confined jets, back step,etc. )
  • Compare with 2D model: verify the assumptions and validity
• Automation of mesh generation and FLUENT setup
• Data/Parameter analysis and recommendations
  • Recognize important variables and parameters
  • Write user defined functions to extract analysis data
  • Investigate the performance of different geometry
