PENGARUH VARIASI JUMLAH SUDU TERHADAP DAYA OUTPUT PADA PROTOTYPE PEMBANGKIT LISTRIK TENAGA MIKRO HIDRO (PLTMH) DENGAN MENGGUNAKAN TURBIN CROSSFLOW

Abstract

Crossflow turbine is a type of turbine that often used as a prime mover in MHP system. thistype of turbine has an advantage witch can be applied in low head with high water discharge. Theoutput power from this turbine is effected by the number of blades that installed on the tubine runner.The aim of this study is to hold an experimental study of the number of blade that used on crossflowturbine to get the maximum output power. The number of blade that used is 10, 14, 18, 22, and 26blades. Where from the result of calculations, it is found that turbine with number of blades 18 hasthe higest efficiency with a value of 8,52%.
