Abstract: A laboratory-scale integrated inclined axis Screw Turbine System simulating pico hydroelectric generation has been constructed in ASPETE, under the supervision of the Austrian B.O.K.U. University and used in the educational curriculum of Renewable Energy Programme at the M.Sc. in “Management Technologies of Waters, Soft Energy Systems and Environmental Mechanics (M.T.W.-S.E.S.E.M.)”. The mainlines of the small integrated Screw Turbine System simulating pico hydropower generation construction and the measurement procedure are described in the present manuscript. The apparatus is simple to make and uses inexpensive components, most of which can be found in standard science laboratories. From the “Management Technologies of Waters, Soft Energy Systems and Environmental Mechanics” M.Sc. courses experimental results, the turbine was found to have a good
maximum mechanical efficiency for small water flow rates. The small scale hydraulic screw turbine and apparatus demonstrate the principles of hydropower and are well suited for educational purposes in renewable and soft energy.
Key words: renewable energy sources, small hydropower, screw turbine, environmental and renewable energy education
