RISExperimental Investigation of Part Load Vortex Rope Mitigation With Rod Protrusion in an Axial Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper investigates the rotating vortex rope (RVR) mitigation on an axial turbine model by the radial protrusion of four cylindrical rods into the draft tube. RVR mitigation is of particular interest due to the ...
On Using the Distributor as a Multi Degree-of-Freedom System to Mitigate the Pressure Pulsation in an Axial Turbine at Speed-No-Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydraulic axial turbines are more frequently utilized for grid regulation purposes. Sometimes, they must be operated at speed-no-load (SNL) conditions, which is characterized for some machines by a varying number of large ...
