“…It may be concluded from this figure that there is a very good agreement between the experimental results and numerical results. Also a comparison of the numerical results was made with that of [9]. From Figure 17 it may be indicated that the comparison has a great consistence with that published data.…”

Archimedes screw turbines have been developed as they work with a low head with high efficiency, where flow energy can be exploited in small rivers, streams, regulators and others. The power can be produced using Archimedes turbines and depends on some parameters including the number of blades, flow, and angle of the shaft inclination and the length of the pitch. A physical and numerical model has been developed to determine the performance of the Archimedes turbine on the Ramadi Dam in Iraq. The physical model was made of stainless steel with the following parameters (length 1000 mm, pitch 70 mm, diameter ratio 0.536, inclination angles 30˚, 35˚, 40˚, 45˚). Work was carried out on different flow rates and inclination angles. The experimental results showed that the highest efficiency was 81.4% at 35˚ inclination angle and a flow rate of 1.12 l/s; the maximum power of 9.03 watts was at a 45˚ inclination angle and a flow rate of 2.065 l/s and 72% efficiency. Also, the impact of the pitch and the number of blades were studied. The results show that torque is increase with an increase in the pitch length, and torque is decreased with increase in several blades. The numerical results showed that the using of two blades led to a greater power produced. The comparison of the numerical and experimental results showed a good agreement, also the comparison with the published data showed a good agreement. As a final result the Archimedes screw has many positive points making it a good potential candidate. The results that emerged show the possibility of using this type of turbine in the Euphrates River in Anbar Governorate-Iraq, as the province is characterized by the presence of many regulators on the river in which turbines can be employed.

“…The geometric shape of Archimedes, as well as flow losses, has a great impact on the efficiency of the screw according to the analytical model presented by taking into account the losses of water due to the Gap between the screw and the casing (Trough) [9].…”

“…As per the different laboratory experiments which have been done that support these claims as compared to other turbines, this new ultra-low head technology is still a niche product [40,42]. The turbine selected in this design work is an Archimedean screw turbine with a screw-shaped rotor/blade inserted on the stator of a rapid pipe fitted with a flow guide on the inlet side and nozzle on the outlet side so that the turbine can be mounted at an elevation close to 22 • .…”

In this paper, a system comprising a solar photovoltaic (PV)/micro-hydropower/battery bank/converter has been designed, modelled, simulated, and optimized for the rural area of Wimana village, Rwanda. The total load has been fairly estimated for the residential electric utility needs. To satisfy the load demand, solar photovoltaic (4 kW) and microhydro (15 kW) power capacity were considered as the main sources of energy to supply electricity. Either in peak load times or during low generation of primary sources, storage battery banks can also be discharged. The simulation and optimization were done based on the load demand, climatic data, the economics of integrated system components, and other parameters in which the total net present cost has to be minimized to select an economically feasible and technically capable hybrid power system. Based on the load profile of the data collected for the village, the daily energy consumption was found to be 180.99 kWh/day with a peak load demand of 18.56 kW. The net present cost and the cost of energy for the optimized power system amount to $78,763.26 and $0.0757/kWh respectively. HOMER Pro simulating software tool was used to design optimal off-grid and energy management systems.

“…In the theory of windmill or water wheel turbines, the blade diameter is related to torque while the blade angle is related to the rotational speed produced. The design of the diameter and angle of the blade must involve the characteristics and availability of energy (Sarkar and Behera, 2012;Saroinsong et al, 2016). In some previous tests, for certain flow capacities, optimal energy was obtained at the blade angle between 60° to 70° (Yulianto et al, 2017).…”

It is an innovative thing to design turbines that are compatible with flat-flow water energy. The turbine that was chosen is a turbine screw model with a non-uniform blade slope. The turbine made with a stator consists of a collector pipe and a quick pipe as a nozzle and a screw-shaped rotor with varying blade spacing. The results of the design are two screw parallel with each consisting of five blades which are installed at 45°, 55°, 65°, 75° and 80° angles. The research methodology used is experimental through theoretical design and practical testing. Tests are carried out in uniform blade angles and compared with combination blade angles. The test results show that the turbine with a combination blade angle has a rotational speed lower than the maximum rotational speed (i.e., at 60° blade angle) but has better rotational stability against load changes. Turbines still have good efficiency even though the rotating speed drops to 60% due to loading.
