Journal ArticleDOI
Experimental Study and Numerical Simulation of the Flindt Draft Tube Rotating Vortex
TL;DR: In this paper, 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 are studied by carrying out both experimental flow survey and numerical simulations.
Journal ArticleDOI
Analysis of the Swirling Flow Downstream a Francis Turbine Runner
TL;DR: In this article, an experimental and theoretical investigation of the flow at the outlet of a Francis turbine runner is carried out in order to elucidate the causes of a sudden drop in the draft tube pressure recovery coefficient at a discharge near the best efficiency operating point.
Journal ArticleDOI
Analysis of the Cavitating Draft Tube Vortex in a Francis Turbine Using Particle Image Velocimetry Measurements in Two-Phase Flow
TL;DR: In this article, a particle image velocimetry (PIV) system was used to investigate the flow velocity field in the case of a developing cavitation vortex, the so-called vortex rope, at the outlet of a Francis turbine runner.
Journal ArticleDOI
Experimental analysis of the swirling flow in a Francis turbine draft tube: Focus on radial velocity component determination
TL;DR: In this paper, an analytical formulation for this velocity component based on the formulation for the conical diffuser and on the three vortices structure is proposed and compared with measurements downstream of the runner include radial component made at CREMHyG (Grenoble) by LDV, and PIV techniques.
Journal ArticleDOI
Experimental PIV and LIF characterization of a bubble column flow
TL;DR: In this article, a complete characterization of a bubble column issued from a metallic sparger with holes of 0.5mm diameter is presented, which is related to the optimization of the aeration in hydraulic turbines with micro-bubbles.
