Project 09454 Design and Testing of Turbomachinery Components

Project 09454: Design and Testing of Turbomachinery Components Project Background: Sponsor: 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.
