Proc. ASME. IMECE2020, Volume 10: Fluids Engineering, V010T10A043, November 16–19, 2020
Paper No: IMECE2020-23378
...Abstract 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...

Paper No: 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...
