| Summary: | Gravitational water vortex power plant is a green technology that extracts energy from
the water vortex. The main advantage of this type power plant is its low hydraulic pressure
requirement that makes this technology ideal for installation at areas with river or stream. In order to
determine the optimum efficiency of the power plant, a model free vortex power generation system
was designed and tested under different water pressure and turbine parameters at Material and
Mineral Research Unit laboratories, Faculty of Engineering, University Malaysia Sabah. The
experimental result showed that the tangential velocity at the vortex free surface was highest for
0.12m water head and the maximum efficiency about 43% achieved with three blades and 0.027m
turbine outer diameter. It was also found that in the model vortex power generation system the
maximum hydraulic efficiency was recorded when the turbine rotating speed was half of the vortex
tangential velocity. The turbine speed had a very week relation with hydraulic efficiency |
