RISAnalysis of the Cavitating Draft Tube Vortex in a Francis Turbine Using Particle Image Velocimetry Measurements in Two-Phase Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Partial flow rate operation of hydroturbines with constant pitch blades causes complex unstable cavitating flow in the diffuser cone. A particle image velocimetry (PIV) system allows investigating ...
Experimental Study and Numerical Simulation of the FLINDT Draft Tube Rotating Vortex
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamics of the rotating vortex taking place in the discharge ring of a Francis turbine for partial flow rate operating conditions and cavitation free conditions is studied by carrying out ...
