Abstract

Gravitational  water  vortex  turbine  (GVT)  is  a  run-of-the-river hydroelectricsystem usedfor   generatingelectricity   in   the absence  of  a  large  dam  and a reservoir;i.e.,GVT generatespower   using   the water natural   flow   rate.   Recently,   the development  of  GVT  is  gaining a  growing interest within  the scientific  community concerning  theadvantagesassociated  with the  technology  in  the  process  of  electric  power production. This work  describes  the  design  of  an  experimental  facility  for  the characterization  ofaGVTin  order  to understand  in  a  detailed waythe effect  of  the  variation  of  hydrodynamic  and  geometric parameters   on   the performance   curve of   the   turbine. The experimental   results   demonstratedthat   a   wider   vortex   is generated  at lower channel  inflow velocities.Additionally,  a maximum  efficiency  of  0.495  at  140.25  rpm  was  found  for the GVT tested.
