Optimization of axial water injection to mitigate the Rotating Vortex Rope in a Francis turbine
Renewable Energy, 2021Abstract Rotating Vortex Rope (RVR) resulting from flow instabilities inside draft tube affects the hydraulic turbine's efficiency and wear. Among the passive and active RVR mitigation methods, the water injection method has been widely investigated lately.

Abstract Rotating Vortex Rope (RVR) has been a matter of focus for years due to the major effects on hydraulic turbine’s efficiency. The exact procedure of RVR formation is still vague. The present research focuses on the dynamics of the RVR formation during the load variation employing transient numerical simulations.

Numerical Simulation of the Rotating Vortex Rope with Code_Saturne
2019 International Conference on ENERGY and ENVIRONMENT (CIEM), 2019The paper presents numerical simulations of the rotating vortex rope (RVR) inside a Francis turbine draft tube. The computational fluid dynamics (CFD) calculations were carried out using the Code_Saturne software. The geometry of the turbine was obtained from the Francis-99 workshops. The mesh files provided for the Francis-99 workshop II were modified
