“…Michell-Banki turbines without section pipe modifications reach efficiencies as high as 42.4 % [21,22]. Next comes the vertical-axis Savonius turbine with variable and constant curvature blades reaching efficiencies between 28% [23,24] and 45% [25], respectively. Then, the Darrieus type turbine is also used for this application, especially the straight-bladed Darrieus with 30% efficiency [26], the spherical with helicoidal blades with 26% [27], and the spherical Darrieus with 40% [25].…”

In-pipe hydraulic turbines are a promising energy-harvesting technology. Recent studies have demonstrated a strong influence of the turbine blade number on the performance of an axial propeller-type turbine. However, limited research has been dedicated to turbine diameters less than 100 mm. Therefore, this research aimed to determine the effect of the number of blades on the hydrodynamic performance of a 75.3 mm diameter axial propeller turbine for in-pipe installation. A parametric numerical study was performed by varying the angular velocity from 1600 to 3800 rpm and the number of blades from 2 to 6. Results identified an inverse correlation between the hydraulic efficiency of the turbine and its blade number and a direct correlation between the pressure head and the turbine torque. Furthermore, the performance showed hydraulic behavior comparable to those found in literature, confirming a similar hydraulic behavior as turbines with diameters exceeding 100 mm. Additionally, the turbine’s internal flow behavior was analyzed by visualizing the vortex structure using the Q-criterion. Lastly, this study provides a deeper understanding of the effect of the number of blades on the hydrodynamic performance of an axial turbine for in-pipe installation.

Water streams with low heads can be found in India, both naturally as well as through irrigation canals. These natural resources can be used to generate electricity by utilising Hydrokinetic water turbines. The current investigation includes an experimental investigation of the axial flow turbine in order to make use of these naturally available resources. For Axial Flow Turbines (AFT), the influence of the fillet radius at the leading edge corner of the runner blade is studied. The experiments are carried out under various turbine loads and corresponding head conditions. The 3D printed runners with six different fillet radius (Rtu), i.e. 0 mm, 2 mm, 4 mm, 6 mm, 8 mm, and 10 mm are examined experimentally. The results are presented in the form of obtained efficiency (η ) with a diverse Fillet Radius Ratio (FRR) for different Tip Speed Ratio (TSR) and equivalent head (H). The results indicate that, at the head, 0.012 m, with a sharp edge, i.e., FRR = 0 (Rtu = 0 mm), the minimum efficiency of 34.90% is recorded. However, at the same water head, the maximum efficiency of 84.82% is achieved with FRR = 0.046 (Rtu = 2 mm).

“…The proposed turbine showed good performance at the velocity rage from 1.5 m/s to 3.5 m/s and the rotating speed range from 100 rpm to 1000 rpm. Yang et al [25] compared the start-up hydraulic performances of a lift-type and a drag-type hydro-turbine. The results showed that the lift-type turbine gives better hydraulic characteristics in terms of tip speed ratio and power coefficient than those of the drag-type turbine, while the drag-type turbine displays better start-up performance than the lift-type.…”

The induction faucet has been widely used in public due to its advantages of convenience, sanitation, water, and electricity saving. To solve the problem of environmental pollution caused by dry batteries used in induction faucets, a suitable micro pipe mixed-flow turbine installed in a tap-water system with only 15 mm in diameter, that uses the pipeline water pressure to generate electricity for the induction faucet was designed and developed, based on computational fluid dynamics (CFD) and model tests. According to the specific speed, a preliminary design of each flow component of the turbine was first produced. Then, using the multi-objective orthogonal optimization method, the optimum test schemes were determined, and the influence of various test factors on the turbine’s hydraulic performance was revealed. Under the design flow rate, the turbine’s power output and efficiency were 6.40 W and 87.13%, respectively, which were 34.45% and 4.99% higher than those of the preliminary scheme. Both the power output and efficiency of the optimized turbine met the design requirements. Numerical and model test results showed good agreement, where the deviation in turbine power output predictions was below 5% under large flow condition. Model test results also showed that the turbine can be started as long as the inlet flow is greater than 0.14 kg/s. Overall, the micro-pipe turbine designed in this paper exploits the (mostly wasted) water kinetic energy in induction faucets for power production, contributing to environmental pollution reduction and realizing energy conservation.
