“…Several studies utilise this measure to compare their novel designs against established models in the market, represented in a normalised form, independent of the system size [10], shown in Figure 5. This is known as the standard capacity (𝑆 ), and used as an indicator of pure delivery capacity [23]:…”

This paper presents a parametric study of the multistorey hydro-powered pump, known as "Bunyip," which has demonstrated significant potential in contributing to rural regions. The study aims to understand the underlying physics of the system and enhance its hydraulic performance. A transient three-dimensional model using the commercial Computational Fluid Dynamics (CFD) tool Ansys-Fluent is utilized to gain insights into the fundamental flow mechanics, operational efficiency, standard capacity, and relative delivery. The investigation involves an initial assessment of performance for three Bunyip devices based on manufacturing data. Parametric analysis is conducted, and a parametric dataset is generated through meticulous application and numerical modelling. The CFD results are validated against experimental data. Three design configurations are considered, and 58 sets of varied input parameters are examined. The best design configuration is evaluated against five cases of conventional hydro-power pump systems. The results indicate that a smaller diameter of the pressure chamber and a higher supply head lead to higher pressure, achieving a target head of 3 m with 15% efficiency and a flowrate of 11.82 l/min.

This paper presents a parametric study of the multistorey hydro-powered pump, known as ‘Bunyip’, which has demonstrated significant potential in contributing to rural regions. The study is aimed at understanding the underlying physics of the system and ways to enhance its hydraulic performance. A transient three-dimensional model using the commercial Computational Fluid Dynamics (CFD) tool Ansys-Fluent is utilized to gain insights into its fundamental flow mechanics, operational efficiency, standard capacity, and relative delivery. The investigation involves an initial assessment of performance for three Bunyip devices based on manufacturing data. A parametric analysis is conducted for the dataset generated through meticulous application and numerical modelling. The CFD results are validated against experimental data. Three main design configurations are considered, and 58 sets of varied input parameters are examined. The best design configuration is evaluated against five cases of conventional hydro-power pump systems. The results indicate that a smaller diameter of the pressure chamber and a higher supply head lead to higher pressure, achieving a target head of 3 m with 15% efficiency and a flowrate of 11.82 L/min.

“…It is a pumping device that allows rising water uphill without using any external power source (Hussin et al, 2017). It only used the water hammer effect to develop pressure from the elevated source, which pushes a certain amount of water to higher elevations in a periodic operating cycle (Fatahi-Alkouhi and Lashkar-Ara, 2019). It has a simple water pumping system consisting of an elevated water source supply, drive pipe, ram pump body with two moving parts (i.e., waste valve and delivery valve), pressure chamber and delivery pipe (Sarma et al, 2016;Hatipoğlu et al, 2018;Asvapoositkul et al, 2019).…”

In response to the continuous price increase of electricity and diesel fuel, a hydraulic ram pump serves as an alternative water pump that can be useful for farmers and lowincome earning citizens living in mountainous areas. However, this pump was observed to have a critical delivery head to work uninterruptedly. This study conducted a field experiment of 10 design cases for drive pipe to determine the critical delivery head of the newly developed hydraulic ram pump using different pipe fittings and a 20-L disposable polycarbonate bottle as a pressure chamber. Results showed that the newly developed hydraulic ram pump reached its highest discharge efficiency of 12.83% and energy efficiency of 84.61% at 9.83 and 10.90 m critical delivery heads, respectively. Results also revealed that the critical delivery head was 86.27% linearly correlated with discharge efficiency and 46.78% linearly correlated with energy efficiency (p < 0.05). Thus, the determination of the critical delivery head provided a baseline reference in ram pump studies that only gave ranges of ratios for the drive head to the delivery head. Furthermore, the newly developed hydraulic ram pump can produce water up to 700 L a day which can be beneficial for households and smallscale agricultural farming.
