1. 2008-2 through 2008-3

2. Introduction  Particle Imaging Velocimetry (PIV) uses a sheet laser beam to illuminate particles that cross the sheet.  The particles will diffract the light of the laser and thereby allow for imaging.  Based on the data gathered from imaging these particles, the flow through the system can be visualized.

3. Starting Point  The existing test system was developed for MSD in 2007 -2 & 2007-3 quarters under P08453  The system consisted of a centrifugal pump that sits within an automated and instrumented flow loop.  The apparatus and pump housing will be fabricated from optically clear materials to allow flow visualization within the pump using Particle Imaging Velocimetry  The system was designed and built with a modular construction so that design variations of impellers, diffusers, and housings may be easily exchanged.

4. Planning

5. Customer Needs  Perform PIV experiments to characterize different flows through the pump system  Use as an teaching tool for undergraduate coursework, projects & labs  Use for Graduate research & projects

6. Deliverables  Design & manufacture interchangeable Impellers & Diffusers (3 items each)  Set up & perform PIV measurement on pump system using new Impellers & Diffusers

7. Mission Statement The purpose of this project is to design & develop interchangeable impellers and diffusers which will work on the existing PIV system in order to characterize different flows through the pump system. Team will deliver 3 impellers & 3 diffusers for the existing system. Furthermore, team will also be responsible for setting up experiments and performing PIV reading using the new impellers & diffusers

8. Constraints  Budget:  Technical Expertise: Not all KGCOE ME students possess the requisite knowledge in Turbomachinery  Time: All deliverables must be performed within the allotted 22 week timeframe  Resources: Impeller and diffuser manufacturing requires precision machining operation  Platform: The project must build upon the existing PIV system (P08453)

9. Assumptions  All roles planned this quarter will be filled during both quarters  Existing test stand can be used and improved for this year’s project  Existing test stand is in acceptable condition  Outsourcing the manufacture of Impellers and Diffusers will not adversely effect the timeliness of the deliverables

12. Intellectual Property Considerations Project will be open source, open architecture Thorough patent research must be carried out prior to starting design phase

13. Team Values & Norms Punctual Thorough Accurate Professional & Ethical Committed Good Communication

14. Team Values & Norms Punctual Thorough Accurate Professional & Ethical Committed Good Communication – Team members should make a conscious effort to keep all members in the team informed with new information, knowledge and project developments, especially the two leaders

15. Required Resources Technical learning materials such as Turbomachinery text books, research papers Access to existing (P08453) PIV pump system Time with Faculty Guide, Dr. Day Access to manufacturing resources: CNC machining, Rapid prototyping or outsourcing CAD & Engineering software packages EDGE

16. Concept Development

17. Customer Needs Customers require a upgraded PIV system to perform reading on more sophisticated flow patterns provided by new impellers & diffusers. The new impellers and diffusers must be interchangeable and must fit with the existing pump system.

18. Brainstorming Questions How can the team best familiarize themselves with turbomachinery concepts? What material can be used to make the impellers & diffusers? Which manufacturing method will be used to make the products?

19. Risk Assessment  Technical expertise of ME student might be inadequate for the design task at hand  Time needed for impeller manufacturing will affect the timeliness of deliverables  Existing PIV module may not function as desired

20. Risk Assessment  Flow parameters are not met by the design  Design stage leaks over allocated time due to complications  Manufacturing resources at RIT might be inadequate to produce the required parts  Budget might be insufficient to cover outsourcing of manufacturing

21. Risk Management  Team Lead, Lead Engineer will work with faculty advisor to develop a plan to learn the technical skills required to design turbomachinary  Team lead will look for alternative manufacturing methods to save time, cost ex: rapid prototyping, outsourcing

22. Risk Management  Lead engineer designs a study plan with the assistance of faculty advisor & consultants to learn the required skills  Project lead allocates excess time for manufacturing parts & reallocate labor & resources to expedite other processes.

23. Risk Management  Lead engineer assigns a plan and adequate labor to ensure that the existing will meet required levels of operation  Lead Engineer will reevaluate and prioritize design goals to ensure timeliness of deliverables

24. Risk Management  Lead engineer will reevaluate design to ensure that products can be manufactured using resources at RIT (while meeting specifications) OR  Project Lead and Lead Engineer will work towards outsourcing the manufacturing to outside vendors

25. Risk Management  Project Lead will work with Faculty Advisor to reevaluate the budget OR  Reevaluate the scope of the deliverable to meet the existing budget
