Water flow in irrigation is a means of obtaining electric power, which is commonly called microhydro. The waterwheel is the main component of the microhydro energy conversion process. The amount of energy converted by a waterwheel depends on the shape of its model, blade shape and the location of the installer. This study aimed to identify the characteristics of optimally efficient waterwheels. In addition to the energy of the place (i.e., the head), the influence of the weight of the water flowing into the blades of the waterwheel must be considered. This study also aimed to determine the effectiveness of mill performance by comparing waterways that use nozzles with those that use open canals. An experimental method was used to design a waterwheel system by testing the efficiency ratio between the nozzle line and the open canal. This test used the following variable water discharge rates: 12 m 3 /hr, 14 m 3 /hr, 16 m 3 /hr, 18 m 3 /hr and 20 m 3 /hr. Using the nozzle line with the largest discharge rate of 20 m 3 /hr, an rpm of 192.7 is produced with a torque of 0.7 Nm. The waterwheel produced 14.13 Watts, with an efficiency of 64.75%. A line that used an open channel at the highest discharge rate of 20 m 3 /hr produced 61.7 rpm with 0.7 Nm of torque and 4.52 Watts with an efficiency of 20.71%. The speed of water flow in the nozzle line was faster than in the open canal path, causing the tangential force on the waterwheel to be greater than on the open canal path. Based on these results, it was concluded that the path was the most efficient when using a nozzle.

In a reaction turbine, the amount of energy harnessed depends on discharge and net head. The two variables are mutually exclusive or in which one variable is dependent on another and in which the increase of head will decrease the flow required by the hydraulic turbine or vice versa. There is a need for improving the existing hydropower system and the method for enhancing the net head of a reaction turbine is essential. The present invention will hold the key in novelty during the design and excavation of tail race channel or for Renovation, Modernization and Uprating (RMU) of the existing old hydro power plants. The proper redesign of tail water channel, selecting suitable width, depth and by adopting flow regulating means will yield improve the net head substantially and thereby saving of discharge to an extent. The present invention enables to improve net head and saves discharge considerably, thereby enhancing the capacity factor of the hydro plant. The novelty and the innovation is granted an Indian patent for the method of enhancing the net head of a reaction turbines.

“…In addition, gravitational vortex turbines are more stable and can operate with lower heads. Mugisidi et al, [3] proposed a novel Dethridge wheel blade shape, which can achieve an efficiency of 71.7%. However, this performance was achieved at a very low rotational speed of about 13 rpm, which can make it difficult to select a suitable generator.…”

The gravitational water vortex turbine (GWVT) is a promising solution to exploit the potential of low-head hydro energy. Previous research has shown that a 3D runner performs better than a runner with a flat blade and a 2D curved blade. This research investigates the performance of a conical gravitational water vortex turbine (CGWVT) with a 3D runner using numerical simulations and experiments. The numerical simulations were carried out with Fluent V 6.1, a 2-phase transient incompressible solver, at various torque loads. Furthermore, experiments were conducted to validate the numerical simulations by varying the torque load and water flow rate. The experiment revealed that the maximum power was achieved at a rotational speed of around 100 to 110 rpm. The maximum efficiency was 0.28 at a flow rate of 0.00477 m³/s. The developed simulation closely matched the experimental results, making it useful for design and prediction for further development.
