Design Team:
 Rishitha Dias - ISE – Project Manager
 Kevin Klucher - ME – Lead Engineer
 John Hayles - ME
 Reme Meck - ME
 Ammar Jangbarwala - ME
Project Background:
 Project Family: Sustainable Technologies for the Global
Marketplace
 Project Track: Flow Visualization
 Sponsor: Dresser-Rand Corp.
 Faculty Guide: Dr. S. Day
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.

 GUI Controls & Valves
 Assembly/Disassembly
averages 3.5 minutes
 PIV Compatible
 Clear Acrylic Components
Results:
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.

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
