The best solution is a custom design system with a runner that works in both the pump and turbine directions. Some vertical turbines may be very short while others may be hundreds of feet long depending on the application requirements. Design Exploration using Star-CCM+ To optimize the Francis Turbine base geometry, three design parameters were strategically varied with hopes of analyzing variable sensitivity in performance: 1. • Mixed -flow pumps –A compromise between radial and axial operate at higher pressures than axial-flow pumps while delivering higher discharges than radial- Pumped hydro energy storage (PHES) is currently the only proven large-scale energy storage technology. Webb ESE 471. K. 1 - 12 , 10. In section two of this manuscript, the optimization method is introduced. Power Plant Configurations – Binary Set Mar 15, 2015 · For energy storage purposes, the goal is to minimize the difference in best efficiency between pump and turbine operation. Characteristics of reversible pump-turbines Advances in technology are constant, including the latest developments on variable-speed and wide head range applications. 1155/2018/6069780 Google Scholar. Frequent changes between pump and turbine operations pose significant challenges in the design of a pump-turbine runner with high efficiency and stability, especially for ultrahigh-head reversible pump-turbine runners. . a=Sigma=Cavitation coefficient knowledge and understanding of the phenomena shall help to improve the profile design and to avoid or minimize these unsteady effects. The pumped storage scheme Tongbai is equipped with four pump-turbines with a rated power of 306 MW each. ; CFturbo. ; George Maddox, Best PumpWorks; Sam Lowry, Simerics Inc. • Axial -flow pumps lower pressures and higher flow rates than radial flow pumps. First, a brief introduction of the strategy was provided. In the present paper, a multiobjective optimization design system is used Sep 1, 2015 · In this study, a design strategy combining 3D inverse design, CFD, DoE, RSM, and multiobjective genetic algorithm (MOGA) was used to develop a pump–turbine runner with high efficiency and stability. First, the inlet and outlet sizes of the pump are determined. In section three, the Oct 23, 2024 · The essential difference between turbines and pumps should now be clear; as turbines are used to create energy out of the fluid movement, and pumps are used to create fluid movement using energy. An example of the complete process used by PumpWorks 610, LLC in designing and optimizing a vertical turbine pump is presented, starting with the creation of an initial prototype using the design software CFturbo, and the subsequent virtual testing and analysis with the CFD tool Jan 30, 2025 · The experimental data on pressure pulsations reveal that throughout the entire flow field of the pump-turbine—including the volute inlet, the region between the movable guide vanes and the runner, the area between the top cover and the runner, and the tailwater pipe—the measured values consistently satisfy the criteria outlined in GB/T Mar 1, 2024 · Optimized blade design of counter-rotating-type pump-turbine unit operating in pump and turbine modes Int J Rotating Mach , 2018 ( 2018 ) , pp. com Wpt=Total pump-turbine weight WR2=Product of the weight of revolving parts and the square of the radius of gyration y=Gamma=Specific weight of water y=Eta=Hydraulic efficiency ng= Eta,= Generator efficiency np=Eta,=Pump design efficiency qt=Eta,=Turbine design efficiency x=pi=3. ABSTRACT. 14159. While the system could have a dedicated pump and turbine, it would greatly increase the overall cost. Further aspects regarding grid integration are discussed. Same with the first-step optimization, the head at the pump design point was also set as a constraint. Calculating the efficiency of a water turbine requires many physical equations, concluding with the ratio of power output from its blades over the Sep 1, 2015 · In addition to the runner efficiencies at the pump design point and turbine rated point, the minimum pressure at the blade surface for both of pump and turbine modes was also set as an additional optimized target. Reversible machine sets consist of a motor-generator and a reversible pump-turbine that works either as a pump or as a turbine depending on the direction of rotation. Among conventional machines, it is found that, for high-flow low-head application, axial flow pump-turbines with variable speed drives are the most suitable. the blade angle at the leading edge of the runner, and 3. pump and turbine operation. May 23, 2019 · Contributor: Yanjun Xia, Simerics Inc. The overall design is presented and several special features of the mechanical design Feb 18, 2025 · Pump-storage power plants use pump-turbines which are reversible machines that can be operated as pumps or turbines.
