1. MSD II –Managerial Presentation Spring 2009 P09454: Design & Testing of Centrifugal Pump Components

2. Design Team: Rishitha Dias - ISE – Project Manager Kevin Klucher - ME – Lead Engineer John Hayles - ME Reme Meck - ME Ammar Jangbarwala - ME

3. Project Background: Project Family: Sustainable Technologies for the Global Marketplace Project Track: Flow Visualization Sponsor: Dresser-Rand Corp. Faculty Guide: Dr. S. Day

4. Project Deliverable: The goal of the project is to design, build, test and deliver to KGCOE, a centrifugal pump system for particle imaging velocimetry (PIV) studies, which can be used both as a teaching tool for undergraduate students as well as a research tool for graduate and faculty researchers.

5. Customer Needs: Primary Customers:  Faculty & Graduate Researchers  Undergraduate Instructors Customer Needs / Target Specifications:  Generate Multiple Flows~ 3 Unique Impeller Designs ~ 2 Unique Diffuser Designs  PIV Compatibility>85% Transmissivity of Pump Components  Lab Teaching Tool< 5 min Component Swap Time > 0.45” Tool Clearance Measureable Flow, Pressure & Power. Parts must withstand a drop from 42”

19. Results:

21. Test Results As head rises, the flow decreases, demonstrating basic pump curve relationships. With the addition of a vaned diffuser, the head generated is increased versus flat ring diffusers.

22. Discussion Pump provides 10x the options (impeller and diffuser) with 65% faster component switch time Head generated is up to 60% greater than previous system benchmarks Flow rate is not up to maximum theoretical value of 22.3 gpm. However, ~ 25% increase over previous iteration Diffuser made a large difference in the amount of head generated, up to a 27% increase for the basic 102 impeller New designs can be rapid prototyped and tested in the test loop within several days based on standard dimensions used for the components
