The combination of Savonius and Darrieus turbines had been proposed with the aim to overcome the weaknesses and complement the strengths from each design. This paper gathers relevant information and provided an extensive review on the combined Savonius-Darrieus turbine for both wind and hydro applications. The paper initially reviews the experimental and computational methodologies utilized in previous research in design evaluation of the turbines. The self-starting capability and efficiency of both turbines were the main concern. Following this, investigations were conducted on the possibility of combining the advantages on the two turbines with respect on the design compactness, radius ratios, attachment angles and rotational velocities.

“…Then, Lust et al, [9] investigated three blades Darrieus water turbine with setup conditions has waves and concluded the rotor degraded power production slightly compared to the current without the waves. Yagmur et al, [10] examined single and double Darrieus water turbines in series. They showed that the numerical results are in good agreement with experimental findings, and the performance of the downstream turbine was lower than the upstream turbine [10].…”

Rice fields are areas that have irrigation and rarely have lighting; this is dangerous at night because wild animals such as snakes are difficult to see. Irrigation has low-scale water energy with low-head conditions; hence the Darrieus and Savonius type water turbines are considered suitable for this condition. However, until now, there has been no comprehensive study of the feasibility of the two turbines for irrigation flow. Hence this study presents the experimental work to explore the performances of the Darrieus turbines Two Blade Different Configuration and hybrid Darrieus-Savonius turbine for irrigation flow. Accordingly, four configurations of the water turbines used in these investigations, i.e., Darrieus turbine with two different blades shape the aerofoil of NACA 0016 and NACA 0020, single Darrieus turbine with the aerofoil NACA 0016, single Savonius turbine, and hybrid Darrieus-Savonius turbine with the aerofoil NACA 0016. The mechanical power of the water turbines was measured using a rope brake dynamometer. The results show that the single Darrieus turbine with the aerofoil NACA 0016 has higher tip speed ratios but a lower torque coefficient than the single Savonius turbine. Then, hybrid Darrieus-Savonius turbine with the aerofoil NACA 0016, the maximum power coefficient lower than other. Furthermore, the single Savonius turbine has the highest power coefficient than the other. And the single Darrieus turbine with the aerofoil NACA 0016 shows that the turbine has higher torque than others. Thus, based on the results, a single Darrieus turbine with the aerofoil NACA 0016 is recommended for application.

“…In comparison, vertical axis cross-flow hydrokinetic turbines are suitable for a greater water depth. Savonius (Mrigua et al 2020) and Darrieus turbines (Yagmur et al 2021) As per the Energy statistical report -2021 released by the National Statistical Office (Government of India), India's total renewable energy reserve is 1,097,465 MW. Small hydropower constitutes only 1.93% (21,134 MW) of the reserve.…”

This article addresses the simulation and experiments performed on a Gorlov Helical Turbine (GHT) by altering the index of revolution of its helical blades. Gorlov Helical Turbine is a hydrokinetic turbine that generates energy from the perennial/tidal source. The paper serves a two-fold purpose: parametric optimisation of Gorlov Helical Turbine with respect to the index of revolution and viability of installing the turbines in river creeks. Nine models of turbines with a diameter of 0.600 m and a height of 0.600 m were generated with different indices of revolution and then subjected to simulation studies. A significant rise in the output torque of the turbine was not observed with the various indices of revolution, even as the probability of finding a section at every azimuthal position is likely to rise. Gavasheli's solidity ratio formula was used to formulate an expression for the output power. The output power as per analytical formulation is 1.11 W, which is of the order of output power obtained through simulation (0.951 W). The studies suggest that 0.25 remains the optimum value for the index of revolution of the helical blades. A model with 0.25 as the index of revolution was fabricated and tested at a river creek. The results were found to agree with the simulations accounting for the losses. The study results could encourage setting up hydrokinetic turbines in river creeks, thereby increasing the grid capacity of SHPs in India.
