Spring 2009 Goals

1. Validation of CFD models in terms of energy dissipation map: compare different turbulence models and with experimental data, and generate a reliable energy dissipation map
   • Further work with 3D k-epsilon realizable turbulence model
     1. Solve the puzzle of different predictions from 2D and periodic 3D models
     2. Run simulation on SGI servers
     3. Check grid convergence of 3D models with different meshes and the sensitivity of the solutions to other parameters (as the mesh becomes finer, the accuracy of solution will converge to certain level and there will be no significant gain from finer meshes)
   • Run simulations with Reynolds Stress Model
     1. Start from 2D simulation, with default parameter settings
     2. Check grid convergence and the sensitivity of the solutions to other parameters
     3. Compare model performance(time,convergence, etc.) with other models
   • Case and literature research
     1. Literature research on turbulence models
     2. Literature research on similar simulation cases
     3. Literature research on experimental data of similar flows
     4. Compare with and analyze similar simulation cases and experimental data of similar flows
2. Data analysis, interpretation, geometry variation and design recommendation
   • Dimensional analysis and statistical analysis of the performance parameters with UDFs
   • Automate mesh generation procedure for vary the geometry
   • Investigate various dimensions and detailed designs to give recommendations
3. Recruit and train more people to join the team to keep this project continuing into next semester
