    Abstract

    Pelton turbine is an engine that facilitates continuous power as a wheel or a rotor continually turns due to the pressure of fast moving water through the bucket, where a bucket receives water from the surging nozzle. The objective of this research was to investigate the highest efficiency among different types of pelton turbine through the modification of bucket volume, bucket angle attack. The experiment was conducted at Energy Conversion Laboratory of Sebelas Maret University. The comparative study among the different parameters shows that the value of maximum efficiency was 19.58%, which was obtained at +15% bucket size and 92o angle of attack. It was gained likely due to the collision produced by the jet water in the middle of the bucket, in which the water loading occupied the large area on the surface of the bucket and promoted the increasing speed. It is expected that the result on the appropriate size and angle attack of bucket of this experiment can be manufactured in the future or develop it for achieving maximum pelton turbine efficiency. Keywords: Pelton Turbine, Bucket volume, Bucket Angle Attack, Efficiency.
