Computational fluid dynamics simulation and geometric design of hydraulic turbine draft tube
Advances in Mechanical Engineering, 2015 Any hydraulic reaction turbine is installed with a draft tube that impacts widely the entire turbine performance, on which its functions are as follows: drive the flux in appropriate manner after it releases its energy to the runner; recover the suction ...

Revista Facultad de Ingeniería Universidad de Antioquia, 2013 Severe vibrations are present on the draft tube of a 95 MW hydraulic turbine operating at partial load. Frequent failures on structural elements of the power plant are produced, due to the hydraulic instability inside the draft tube; mainly when the ...
