Francis Turbine Operation at Excess Flow Rate Using Large Eddy Simulation: The Effect of Water Injection

Muhannad Altimemy, Justin Caspar, Saif Watheq, Alparslan Oztekin
Proc. ASME. IMECE2020, Volume 10: Fluids Engineering, V010T10A043, November 16–19, 2020
Publisher: American Society of Mechanical Engineers
Paper No: IMECE2020-23378
https://doi.org/10.1115/IMECE2020-23378
... Abstract High-fidelity Large Eddy Simulations (LES) were conducted to characterize the spatial and temporal structure of turbulent flows in an industrial-sized Francis turbine running at 120% of the design flow rate. Injection at a 4% and 8% flow rate is applied and investigated as a mitigation...

Large Eddy Simulations of Francis Turbine Operating at Ultra-Low Loads

Muhannad Altimemy, Justin Caspar, Saif Watheq, Alparslan Oztekin
Proc. ASME. IMECE2020, Volume 10: Fluids Engineering, V010T10A044, November 16–19, 2020
Publisher: American Society of Mechanical Engineers
Paper No: IMECE2020-23380
https://doi.org/10.1115/IMECE2020-23380
... Abstract High-fidelity large eddy simulations (LES) were conducted to characterize the spatial and temporal structure of turbulent flows in an industrial-sized Francis turbine. The unit operated at 50% and 40% of the best efficiency design flowrate. Contours of vorticity, velocity, pressure...

Simulation of Blank Design for Blades of Francis Turbines

Zhengkun Feng, Henri Champliaud, Michel Sabourin, Sebastien Morin
Proc. ASME. IMECE2012, Volume 3: Design, Materials and Manufacturing, Parts A, B, and C, 23-30, November 9–15, 2012
Publisher: American Society of Mechanical Engineers
Paper No: IMECE2012-86427
https://doi.org/10.1115/IMECE2012-86427
... The metal pressing process which is widely used in many industries has advantages over casting process for producing large and thick blades of Francis turbine. For the design of pressing process, blank design should be firstly performed to determine the dimension of the flat blank. In fact...
