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
