Gravitational Water Vortex Turbine with Two Types of Runner Blades
Water vortex power plant (WVPP) utilises the natural behaviour of water to form the free surface water vortex for energy extraction. To the author’s finding, low efficiency was reported for WVPP systems. As part of the system, water vortex turbine contributes a big portion of the efficiency losses....
