Archimedean Screw Power Generation

Abstract

To design a prototype of screw turbine for power generation using principles of velocity vector. The conception of a screw turbine rotor for remote area electricity production. 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. Energy crisis around the world encourage researcher to pay attention in founding alternate sources of green energy these days. A lot of research has been conducted by using natural energy sources such as solar, wind, wave and water. According to sources of energy from water to run a turbine, there is a rapid change of technology in using such turbine which suitable for definite kind of flow river, much of them are used for high head (differences) to produce electricity.

Micro-hydro power plant based on Archimedes Screw turbine is a type of renewable energy power plant is, easy to be functioned and operates on low costs, etc. The micro-hydro project designed to be a run-of-river type, because it requires no reservoir in order to power the turbine. The water will run straight through the turbine and back into the river or stream to use it for the other purposes. This has a minimal environmental impact on the local ecosystem. The choice of the turbine type depends mainly on the site head and flow rate. The turbine power and speed were directly proportional with the site head, but there were specific points for maximum turbine power and speed with the variation of the site water flow rate. The turbine efficiency could range from 80 to 95 percent and the generator efficiency about 90 percent.
