“…Also, the calculations used to generate the results are not provided. Therefore, the high efficiency and power claims, particularly in [29] need to be verified. Finally, there appears to have been little attempt to review and build on advances made in the area as none of the studies make reference to one another.…”

“…The final experimental paper found by the authors describes a prototype model of an 8-blade vertical axis turbine placed in the centre of a cylindrical tank (1.2 m high and 1.5 m in diameter) with a tangential inlet and a central outlet at the base [29]. The crucial parameters for vortex strength are listed as inflow rate, tank radius and height and outlet diameter.…”

Abstract-Globalenergy consumption is growing considerably, raising such issues as increased energy-related greenhouse gas emissions, reduced security of supply, and growing fuel costs. Renewable resources, such as hydropower, offer an alternative energy source to meet the growing demand. Small hydropower (SHP) has been a major focus of hydropower research in recent years, as many of the large scale hydroelectric opportunities around the world have already been exploited. In particular, low head SHP is gaining interest as traditional turbines, such as the Kaplan and Pelton turbines, are typically limited to heads greater than 3m. Gravitational vortex hydropower (GVHP) is one such low head hydropower solution. GVHP exploits the energy available in a vortex flow, enabling hydropower generation at heads as low as 0.7m. A vertical axis turbine is placed in the centre of a vortex flow and rotates with the flow, thus generating mechanical energy. This paper describes a parametric experimental investigation of the operating conditions of GVHP. Various flow rates, inlet conditions, blade sizes and blade numbers were tested and the turbine rotational speed, vortex height and applied resistance force were recorded for each setting. The power input, power output and efficiency were then calculated and compared for the various settings. It was found that the turbine efficiency increases with blade size and blade number for the blade configurations tested. Maximum power outputs were found for the largest flow rate tested and when there was a considerable resistance force applied to the turbine. Finally, of three inlet heights tested, a height of 25 cm above the tank base (35% of the overall tank height) was found to be optimum for turbine performance. These results have implications both for future research and for practice, with energy generating applications in low head rivers and in wastewater networks.Index Terms-Clean energy, experimental model, gravitational vortex hydropower (GVHP), low head, new energy device.

“…The first primary invention of the GWVPP was in 2004 so researchers have paid a few attentions to the development and optimization of the basin and blade. Experimentally validated that for the same flow rate and same head conditions the output power produced by GWVT is greater than any other low hydropower turbine Venukumar (2013). Completed an in-depth experimental analysis to investigated the effects of various inlet conditions, size, length and quantity of blades on turbine torque, rotational speed and vortex height Power et al (2016).…”

“…The study found that the utmost energy is harvested if the turbine is installed closed to the outlet of the basin. [8] also produced electricity through the use of artificial vortex power generator which includes eight inverted cone design blades. The prototype succeeded to produce more than 150W of electricity.…”

In Malaysia, usually an electricity energy is generated based on fuel sources such as coal and natural gases. Since the consumption of electric energy is keep increasing yearly, the extinction of these sources becomes one of the main problems in this industry. Thus, the country needs to spend higher expenditure to import these sources since it has limited quantity and it is not a renewable energy source. In addition, the usage of the coal as sources affect the environment. Therefore, this research proposed a prototype of mini generator based on the principle of water flow pressure. The prototype is developed based on the flow of water vortex that is influenced by gravity and has the capability to generate energy at low-head flat geographically area. A controller for this system is designed by using Arduino. The objective of this research is to study the efficacy of this type of generator since it is one of the techniques to generate electricity. The efficiency of the designed prototype is analyzed based on different radius value of the basin and the effect of different type of motor used to spin the turbine. The results show that the smaller radius of the basin and direct drive motor generate higher voltage if the system is being tested individually. However, if both characteristics are combined together, the highest radius of basin with direct drive motor produced bigger value of voltage.
