Please read through this list before ranking your preferred teams. Don't worry if you're not sure what everything means. Returning team members, Monroe, Julie, Matt, and Heather will be more than happy to get you up to speed. Just use this as a guide to see generally what kinds of things the teams are working on. Check out each team's page on the wiki for a more basic description of what they do and to see what work they've already accomplished.

Design

Challenges for Fall 2009

Subteam Leader: Heather Reed

Number of team members needed: 9-10

...

• The pieces that allow the sedimentation tanks to be shut off need to be drawn (caps for the inlet channels, and exit channels). In addition, the caps should have a 1" PVC pipe that extends above the surface of the water in order to prevent air being trapped in the pipes delivering flocculated water to the sedimentation tank, and also to serve as a handle for removing the caps.

Chemical Dose Controller

Challenges for Fall 2009

Subteam Leader:

Number of team members needed: 4

...

• MathCAD
• Process Controller
• Fluid Dynamics

Challenges

Non-Linear

...

Chemical Dose Controller

• Determine whether a single or multiple orifices should be used to connect rapid mix chamber and flocculation for optimum energy dissipation, head loss, and float sizing.
  • We have tentative results in the mathCAD file however, we did not have enough time to optimize the functions created.

Computational Fluid Dynamics (CFD)

CFD 3D Floc Tank Simulation Challenges for Fall 2009

...

• Fundamental fluid mechanics
• Basic idea of flocculation mechanisms, easier to learn with fundamentals of fluid mechanics
• Rough idea about computational fluid dynamics or numerical methods, but not a must
• Previous experience with FLUENT is great, but not a must
• Basic programming skills, C is great but not a must at all (sometimes we will use C to write some user-defined-functionfunctions)

Challenges

The long-term goal of the CFD team is to help augment our understanding of hydraulic flocculator, and together with other research teams, to provide for a guideline for design and operation of hydraulic flocculators.

• More simulation for 2D performance parameter analysis: we had some encouraging results and possible future topics are:
  • Further analysis for the current data: change within one flocculator from baffle to baffle, etc.
  • Simulations with different Reynolds number
  • Other ways of varying the geometry: different numbers of baffles, baffle spacing, etc,that encoutered . encountered in design
  • Further develop the formulation of parameters
• Extend to 3D model:
  • Improve convergence, to which energy dissipation rate is very sensitive
  • Congifuration Configuration of parallel computing for 3D simulations
  • Modify the mesh: check the regional convergence of the mesh, coarsen the mesh in some region
• Validation
  • Sensitivity analysis of other parameters when necessary
  • Find some experimental data to compare (or some better idea?)

Floating Flocs

Subteam Leader:

Tanya or anyone with previous knowledge of floating flocs problem

...

• Adobe Photoshop to aid graphics design
• Adobe Illustrator to create brochure layout
• Effective communication skills
• Leadership skills
• Knowledge of advertisement, business, media communications
• Creativity and ingenuity
• Spanish language knowledge is a plus

Challenges

• Get more team members involved with presentations
• Try to pull together a fact sheet for presenter. Those would be good additional info to present other than the ones already on the slides. 
• demo plant suite case maintenance
• Edit the Wiki to weed out outdated information
• Update the brochure with new projects
• Ensure continued bi-annual updates through newsletters
• Enforce the standardized Wiki format by constant updating (not just at the end of the year)
• Translate Wiki into Spanish including navigation menu as well as content
• Assign specific subgroups within PR such that different types of PR can be accessed more efficiently. I.E possibly set up subgroups of PR that deal with local pr, state/national pr, campus pr, student assembly/RSO/greek life/ sports team pr.
• Broaden the medium for pr. I.E. radio, newspapers, magazines, journals, pamphlets, brochures, banners, t-shirts, stickers, posters,etc.
• Establish a calendar of pr events in August that seeks to promote the project itself while incorporating pr events that surround fundraising, presentations, etc.
• Draw in students from business, entrepreneurial majors, marketing, advertising, etc.
• Integrate the PR team with the AguaClara student group by establishing it as a subset of the group itself.
• Work with Partnership for Honduran Health on campus to continue planning their health survey of our technology.
