KAJIAN EKSPERIMENTAL PENGARUH BENTUK SUDU TERHADAP UNJUK KERJA TURBIN HELIK UNTUK SISTEM PEMBANGKIT LISTRIK TENAGA MIKRO HIDRO (PLTMH)
Abstract: Electric energy
demand in Indonesia is currently growing and is still dominated by energy-based
fossil fuels, such as petroleum and coal. Fossil fuels are not renewable
energy, so that when exploited continuously then fossil fuel reserves will be
exhausted.
In addition there are also areas where geographical conditions which do
not allow the electrical networks up to the community. It needs to be made an
effort to supply electrical energy needs by utilizing existing and potential
conditions on the area such as energy of water flow. One of the turbines that
can be used to harness the energy of water flow is helical turbines. The
parameters for the use of a turbine is one form of helical blades (NACA), where
the form of the blades (NACA) it affects the style of the lift and drag forces
helical turbines. On the research study was performed experimentally on effect
shape of blade of the helical turbine blades form by varying the shape of
turbine blades NACA 0020, 0025 and 0030 with number of blades as much as 3
pieces for each form of blades. From the results of testing the turbine
efficiency is obtained by helical 33,97% on the operation of the turbine blades
with NACA helical 0030 and water flow rate of 0.8 m/s with a given light load
of 130 Watts.
