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.

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
