Computational Analysis of Hydro-powered Bunyip Pump

Abstract With the emerging energy demand, water shortage in rural areas, electric supply challenges, and urgent needs for net zero technologies, there has been a recent response with alternative Hydro-Powered Pumping (HPP) technology, known as Bunyip. The recently developed system continues to build commercial success, designed overcome several limitations associated previous technology of Hydraulic Ram Pump (HRP) system, such capacity, height leakage issues. This paper is aimed at providing in-depth investigation into HPP possible further hydraulic enhancement, using CFD parametric analysis. could provide an insight fundamental flow mechanics, operational efficiency, standard relative delivery. comprises initial manufacture data appraisal performance three devices. We paired our analysis meticulous application numerical modelling gather dataset, validate against physical testing data. One key finding was that delivery head 50 m, 6 L/s 4 m head, resulted efficiency 12% respect delivered volume ‘wasted’ through discharge. Thus, order facilitate some distinguishing features Bunyip, sacrificed value lower than comparable HRP.
