inlet tip angle, inlet hub angle, propeller turbine, hidrpower, ultra low head


Potential of Indonesian hydropower which has only been utilized 9% has been concern of many researchers. Hydro power, especially on streams with Ultra Low Head (ULH), has become a trend of current research as renewable energy in reducing the energy crisis as a pico scale power plant. ULH which is often identified with horizontal flow can be utilized well with reaction type turbines, which are often used are propeller turbines. Propeller turbines that have high efficiency still need to be investigated and developed in order to produce better output power, especially in horizontal flow. Modification of experimental blades at inlet section of tip and hub of blade is an effort to increase the output power of propeller turbine. Inlet tip angle variations are 19°, 23°, 29°, and 36°, while inlet hub angle variations are 33°, 36°, 40°, and 44° by being tested at a discharge of 13 l/s. This study aims to determine the effect of inlet angle of tip and hub of blade on the performance of turbine on horizontal flow in pipe. The highest results in use of 23° inlet tip and 33° inlet hub are 17.4 watts of electrical power and 50% efficiency.
