Abstract
This article presents a system that makes use of water hammer pressure surges, which occur when a fluid is subjected to a sudden change in momentum, to drive a piston-crank mechanism for power generation. Given that the magnitude of a water hammer is dependent upon the change in momentum experienced by the water, rather than the initial momentum itself, such a device may have applications operating as a pico scale hydropower device. The results of an experimental study are detailed, showing that a scale-model has a peak mechanical efficiency of 25.7 % and a mean efficiency of between 0.3 - 1.7 %. Potential applications for the technology, namely pico-scale hydropower generation and energy recovery from surge tanks, are also discussed. Keywords: Pico hydropower, Water hammer, Hydraulic ram pump, Hydraulic engine, Surge tank
