“…The design of the Archimedes screw pump (ASP) chosen in this study is based on the geometry used from previous researchers [10][11][12]. The simulations are used to examine the impact of these three design parameters, namely the slope inclination angle (α), the number of bladed screws (N), and the angular velocity (ω).…”

“…However, only three design parameters were considered in the study, that are the angle of inclination, the number of blades, and the angular velocity of the rotating pump. These three design parameters are selected as many previous findings [7,[10][11][12] were focusing on varying angle of inclination with number of blades with constant rotational speed which the highest efficiency can be obtained in this study with different configurations of these three parameters simulated using ANSYS-CFX.…”

“…Based on prior design concept [10] three angles of inclination (20°,30° and 35°), with three variation number of blades (1, 2 and 3) on the screw are varied accordingly. Then series of simulations are performed by considering three different screw rotational speeds of 25 RPM, 30 RPM and 40 RPM which have been applied to smaller size pump of 1 meter in length [11]. The chosen design parameters are to find the highest efficiency which could be applied to small applications (ie home usage) such as in rural areas for flood mitigation.…”

“…By understanding the geometrical parameters of ASP, the mechanical efficiency of ASP can be fully maximized. The parameters are rotational speed, slope angle, and number of blades [10][11][12]. A study discovered that increasing mass flow rate and the number of blades increased torque and efficiency while increasing angle of inclination caused it to decrease [7].…”

Utilization of Archimedes screw pumps as water lifting pumps has become widespread in past decade due to frequent occurrences of floods in Malaysia. The problem of insufficient drainage in various urban areas exacerbates the impact of heavy rainfall, prompting efforts to mitigate this issue with minimal maintenance cost and low impact to the environment. Thus, this study is aiming to study the design parameters of screw pump to obtain the optimal efficiency of the Archimedes screw pump specifically for flood mitigation in Malaysia. The main design parameters affecting pump’s efficiency are rotor profile, pitch length, length of the pump, rotational speed, inclination angle, and material selection. However, only three design parameters were considered in the study, that are the angle of inclination, the number of blades, and the angular velocity of the rotating pump. These three design parameters are selected as many previous findings focusing on varying angle of inclination with number of blades with constant rotational speed. Thus, this study will find the highest efficiency when these three design parameters are integrated with variation of rotational speeds at 25, 30 and 40 RPM. Basically, screw pump is designed using SOLIDWORKS and simulations with specific boundary conditions are conducted using the ANSYS-CFX software, which utilizes computational fluid dynamics (CFD) techniques. These boundary conditions are based on previous study by Rosly et al in 2016. The inlet flow rate of 0.002 m3/s and diameter of the screw pump are constant while the other three main parameters are varying within the acceptable ranges which are reported from prior studies. The outcomes found that the highest torque is generated by a single rotating blade at 5.65 Nm which rotates at 30 RPM at 30° angle of inclination. Meanwhile, the highest efficiency of 24.04% is obtained with a single rotating blade at 40 RPM with 20° angle of inclination. Based on the findings, it is concluded that these three main design parameters of screw pump may not be sufficient to obtain the optimal efficiency for the specific boundary conditions used in the simulation study. Thus, several combinations of design parameters should be considered in the future to increase the screw pump’s efficiency.

“…Further tests were conducted on 16 unique, laboratory-scale ASGs-the resulting data were analyzed in different ways to isolate the effects of specific parameters on performance [101,102,121,129]. The apparatus also allowed adjustment of inclination angle [113,130], addition of an inlet channel modification [131], and tests of screw pump performance [132].…”

Archimedes screws have been used as pumps since antiquity and have more recently been implemented in micro-hydropower plants as an ecologically advantageous technology. They are regarded as a hydropower technology with lower environmental impact since they allow safe passage of aquatic flora and fauna through slow turning, widely spaced blades during operation. Archimedes screw generators (ASGs) operate at river-to-wire efficiencies at approximately 75% with relatively low installation and maintenance costs when compared to other hydropower technologies of the same scale. ASGs are relatively simple and cost-efficient to manufacture-simple enough to create in the seventh century BCE. Modern manufacturing techniques for sheet metal and fabrication have refined ASG production. The literature contains various parametric models for predicting screw power output, and more recent numerical simulations have provided insight into the fluid mechanics of screw generators. The knowledge gained from these studies has allowed researchers to suggest more optimal designs for Archimedes screws. However, much can be done to further improve the accuracy of power prediction models. This paper discusses the current state of the literature for ASGs, and highlights areas for future research to improve power prediction and optimization capabilities for researchers and industrial designers. Highlights• Archimedes screws are an ancient pumping technology that have more recently found use as a hydropower-producing technology.• Archimedes screw generators (ASGs) are a small-scale hydropower technology that may be installed as a run-of-river installation.• ASGs are an eco-friendly technology that allow for the safe passage of sediments, small debris, fish, and other aquatic wildlife through their flights during operation.• There are few experiments and computational fluid dynamic simulations that have sought to extend the literature's data on ASG operation.• Current performance models for ASGs lack robust validation to be properly implemented in power plant design.
