Part Load Vortex Rope as a Global Unstable Mode

Journal of Fluids Engineering, 2017
Renewable energy sources (RES) have reached 23.7% of the worldwide electrical generation production in 2015. The hydraulic energy contribution amounts to 16.6% and comes mainly form large-scale hydropower plants, where Francis turbines represents 60% of the generating units. However, the future massive development of RES will require more advanced grid

Experimental Investigation Of Couple Precessing Vortex Ropes In A Hydraulic Vortex

Siberian Journal of Physics, 2016
The work is devoted to the experimental study of the interaction of the precessing vortex pair in the hydrodynamic vortex chamber. Swirling flow was created by a 12 tangentially directed rectangular nozzles. Design swirl number was varied in the range 0÷6.6 based on the geometry of the swirl device.
