Hydropower is one of the most sustainable and desirable renewable energy sources. Gravitational water vortex hydro turbine (GWVHT) systems are one of the most suitable and sustainable renewable power generation devices for remote and rural areas, particularly in developing countries, owing to their small scales and low costs. There are various GWVHT systems with different configurations and various operating conditions. The main components of a GWVHT system include the inlet and outlet channels, a basin, and a turbine on which there are a number of blades attached. This paper presents a comprehensive review regarding the progress and development of various GWVHT systems, covering broad aspects of GWVHT systems, particularly various types of basins, inlet and outlet channels, turbines with blades which have different shapes, orientations, sizes, numbers, etc. The nature of the previous studies is summarised. The fundamentals of the vortex dynamics involved and the quantitative analysis of the performance of GWVHT systems are also described. The turbulence models and multiphase models used in some leading numerical simulation studies have been reviewed. As a case study, the implementation of a GWVHT system in PNG is presented. Based on the review of previous studies regarding GWVHT systems, the major issues and challenges are summarised, and some key topics are recommended for future research work on the performance of GWVHT systems.

A type of micro-hydropower turbine known Savanious horizontal water turbine operates in freely flowing water of streams, canal, rivers etc. In a current study, blade shape and flow rates were used as the basis for an experimental assessment of a single- stage savanious horizontal water turbine. Numerical, experimental and statistical methods have used to examine the impact of blade shape and flow rates on performance metrics like rotational speed, torque and efficiency. The finding indicates that round curved blades performed better than semicircular and straight curved in terms of overall performance such as torque, rotational speed and efficiency. The performance comparison in term of efficiency amongst round curve blade, semicircular blade, and straight curve blade is carried out and found the maximum efficiency of 47.7%, 39.5%, and 36.5% at respectively at their corresponding speed of water 0.004 m³/s. However, the turbine's performance over optimum flow rates of 0.004 m³/s was found to be decreased due to the increase of water depth and higher water pressure. Moreover, output response was found to be significantly impact by all input parameters through ANOVA method.

“…Therefore, GWVT, a small hydraulic turbine, should be designed to produced power from the low head and low water flow rates (Campbell, 2010;Nishi and Inagaki, 2017b). The installation of GWVT mainly on the bank of the river, water stream, and irrigation canal to enhance electrical energy for a small village to a few houses or a provide electricity to small industries (Dhakal et al, 2016, Sharif et al, 2020. As no water reservoirs and dams are required, civil work is reduced, reducing the capital cost (Venukumar, 2013).…”

“…Such type of microhydro power turbine can be installed in running river systems (Hoseinzadeh et al, 2020a, b). Numerous GWVT can be operated at the same river, irrigation canal, and water stream without affecting the water flow and the output power of one another Sharif et al, 2020). The GWVT generates more power output than conventional turbines on the same head and flow rates (Chattha et al, 2017).…”

Gravitational water vortex power plant is an emerging technology among various micro hydropower plants because of its low head, cost-effectiveness, environmentally friendly and minimal installation and setup time. In the present study, the performance of single-stage gravitational water vortex turbine assembled in a conical basin with curved blade has been analyzed at different head and flow rate to investigate the performance parameters such as vortex formation, vortex height and rotational speed. In addition to that, the influence of vortex formation, vortex height and vortex shape on rotational speed is also investigated. A two input factors, i.e. water head and flow rate, and each having five-level has been selected in a present study. The results showed that at median head 0.70 m and flow rate 0.004 m³/s, the maximum rotational speed 172 rpm and vortex height 0.59 m, respectively, with strong and fully developed air core is achieved which results in high output power and efficiency. However, the water disturbance, weak shape vortex formation and decrease in the vortex height and rotational speed occurred at a minimum and maximum inlet head of 0.6 m and 0.8 m and flow rates of 0.002 m³/s and 0.006m³/s flow rates, respectively, which results in a decrease in the overall performance of Gravitational water vortex turbine. Further, the vortex formation, vortex height and vortex shape strongly influence the rotational speed. Overall, 0.7 m head and 0.004 m³/s developed a strong vortex with a rotational speed of 172 rpm and vortex height of 0.59 m. Furthermore, Analysis of Variance was performed to investigate the percentage contribution and significance of each input parameter on response.
