SwRI will be exhibiting at the ASME Turbo Expo Virtual Conference. Visit our booth, speak with our staff, and join our presenters for the sessions below.
September 21, 2020, 09:45 AM EDT - 11:45 AM EDT
Session 44-04: Large-scale Thermal storage and Power-to-gas Energy Storage
“Cycle Considerations for the Conceptual Design of a Pumped Heat Energy Storage System,” Dr. Natalie Smith
This paper discusses a conceptual cycle design of a recuperated PHES system, specifically examining the effects of turbomachinery and storage temperature on the overall cycle and RTE. Key challenges for cycle design include operating state points for the compressor and turbine that are significantly different from one another in charge mode and discharge mode. The decision to include one or two drivetrains effects turbomachinery performance, cycle optimization and overall cost. Initial design point machine sizing and machine selection for a small-scale demonstration system are also discussed.
September 22, 2020, 09:00 AM EDT - 10:00 AM EDT
Session 25-02: Oil bearings 2
“Novel Approach for Optical Characterization of Thrust Collar Lubricated Area: Experimental and Numerical Results,” Dr. Thomas Kerr
The following paper introduces a new test rig that optically characterizes the thin film region of a thrust collar. The test rig geometries, speeds, and loads match those typically seen in IGC applications. This work will help original equipment manufacturers model TCs more accurately to ensure safe and efficient operation.
September 25, 2020, 12:45 PM EDT - 02:15 PM EDT
Session 29-34: Power Cycles and Testing
“Development and Testing of a 10 MWe Supercritical CO2 Turbine in a 1 MWe Flow Loop,” Dr. Jeff Moore
This paper describes the design, commissioning, and testing of the 10 MWe turbine in a 1 MWe test facility including description of pressure containment, rotordynamics, thermal management, rotor aero and mechanical design, shaft-end and casing seals, bearings, and couplings. Technology readiness of the turbine and heat exchanger technology will be discussed.
