Preliminary Design of Archimedean Screw Turbine Prototype for Remote Area Power Supply

Abstract

This paper is aimed to design a prototype of screw turbine for
power generation. Using principles of velocity vector, the
governing equations have been identified for an ideal case of
force acting on blade. The paper also describes the conception of
a screw turbine rotor for remote area electricity production. The
research is done by calculating based on theoretical way and
compared with experimental results. Output power can be
generated by this small size of turbine is 0.236 watt theoretically
and 0.098 watt experimentally. Various losses in the system are
discussed, which is also demonstrated that the experimental
power outputs and theoretical predictions has a discrepancy.
However, it has a great potential to be used for remote area to
generated power by using low head water source as this research
is developed.
