Sponsor: Project 09454: Project Background: Team Members: The project will build off of a centrifugal pump system test stand developed under MSD project P 08453. The test stand is used for Particle Imaging Velocimetry (PIV) research at RIT Mission Statement: The primary objective of this project is to design, manufacture and integrate several Impellers and Diffusers into the existing pump to enable the characterization of a variety of flows. Key Uses: • Tool to facilitate Particle Imaging velocimetry (PIV) research at RIT • Teaching tool for Undergraduate Turbomachinery Coursework and Labs System Level Design: L to R: Ammar Jangbarwala (ME), Rishitha Dias (IE), Reme Meck (ME), Kevin Klucher (ME), John Hayles (ME), Dr. S. Day (Faculty Guide) Key Customer Requirements: • Must simulate and characterize a variety of unique flows thought the pump system. • The turbomachinery components must be interchangeable to ensure reparability and upgradability • The component swap out procedures must be intuitive and quick (<5 min) • The system must be capable of measuring and controlling variable of interest (Pressure, Flow, etc. ) • GUI to control/measure variables via computer Final Impeller & Diffuser Designs: P 09454 -102 P 09454 -103 P 09454 -104 Design Parameters: To demonstrate effective turbomachinery design parameters, the impeller geometric properties were varied according to known equations regulating flow through a centrifugal pump. The vortex effect was minimized, along with the cavitation, to boost performance to higher levels than the previous benchmark of straight-bladed impeller performance. Specific Speed is used to determine the type of centrifugal pump needed for a certain fluid systems required flow (Q) and system head (H) needed to overcome. Pump head and flow are determined by impeller size and geometry. The flow is a resultant of Diameter, Rotational Speed, Blade Height and flow coefficient. The flow coefficient is determined graphically using the type of blade shape and the blade inlet and exit angle. System Head Equation Specific Speed Equation Flow Test Results: Results Summary: • Characterizes 10 x more flows (5 impellers x 2 diffusers) than previous system • 65% Faster component change-out time • 60% Increase in head over P 08453 pump • 25% Increase in flow compared to P 08453 • 27% Increase for the basic 102 impeller due to Vaned Diffuser Design • Pressure, Flow and Motor RPM can be measured & controlled remotely via GUI P 09454 -105 P 09454 -203 (Vane) P 09454 -106 P 09454 -201 Flat Plate
