Abstract
Constructing a small-scale hydroelectric power station that can run efficiently at a head lower than 10 m is one possible
method for reducing the impact of the electricity crisis in remote areas of Indonesia. The Archimedes Screw turbine is one
type of turbine that is ideal for discharges below 10 m. In this study, the simulation results show that the value of
Turbulences Kinetic Energy is directly proportional to the increase in flow rate but inversely proportional to the level of
immersion. This type of turbine is unless well in Indonesia due to a lack of information regarding the application of low
head power plants. The turbine model that is suitable for the low head is investigated in this study. Before being tested, the
turbine is first designed theoretically and then numerically evaluated. With discharges of 1 l/s, 2 l/s, and 3 l/s and turbine
immersion levels of 30%, 50%, and 70%, ANSYS CFD (Computational Fluid Dynamic) software was used to investigate
flow rate and level of immersion in the turbine. According to the investigation findings, the discharge has a considerable
impact on the turbine's movement; the higher the flow rate, the higher the power to the turbine, which produces a torque
on the turbine. The simulation findings indicate that the value of Turbulence Kinetic Energy is proportional to the increase
in flow rate but inversely proportional to the level of immersion.
