Analysis and development of a stream-powered coil pump

This project is concerned both with a mathematical analysis of the characteristics of the rotating coil pump and the development of a working stream-powered unit designed to be appropriate to the needs and resources of developing countries. Many laboratory tests were carried out on various configurations of the pump's operating parameters, and the results obtained were used to formulate theories for the internal workings of the pump and its response to imposed conditions. A small-scale working model incorporating a chevron bladed water wheel and a coil pump was constructed and tested in a laboratory flume. A larger field test model based on this design was then constructed using a scrap oil drum and other materials considered to be readily available in developing countries. Successful field tests were carried out in a local stream and improvements made to the original design.
