2008-2 through 2008-3
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.
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.
Planning
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
Deliverables
Design & manufacture interchangeable Impellers & Diffusers (3 items each)
Set up & perform PIV measurement on pump system using new Impellers & Diffusers
Mission StatementThe 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
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)
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

Intellectual Property Considerations
• Project will be open source, open architecture
• Thorough patent research must be carried out prior to starting design phase
Team Values & Norms
• Punctual• Thorough• Accurate• Professional & Ethical• Committed• Good Communication
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
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
Concept Development
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.
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?
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
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
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
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.
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
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
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
