“…16, providing maximum power coefficient at an overlap ratio of 0.21 using CFD simulation [106]. Experimental work performed by Yaakob et al [107] at UTM validated the result of the numerical simulation, that two paddles and double stacking Savonius turbine with an overlap ratio, β¼0.21 has high performance, C P ¼0.15, and a prototype provided power of about 1426 W.…”

“…Ismail [109] attempted to increase the efficiency of a Savonius turbine explored and constructed by Yaakob et al [104,107] using a different number of deflectors. He showed numerically and experimentally that two deflectors can obtain a power coefficient of 0.265 in comparison of one deflector or without a deflector, as shown in Fig.…”

Summary Increased demand of energy leads to exploration of new sources of energy. In the last few years, hydrokinetic energy technology emerged as an important area in the field of renewable energy generation. Various hydrokinetic turbines have been studied and used to harness the hydrokinetic potential. Among all hydrokinetic turbine technology, cross‐flow hydrokinetic turbine is considered as the most suitable approach for the riverine system. There are various configurations of cross‐flow hydrokinetic turbine exist for hydrokinetic energy extraction. A number of numerical and experimental studies were carried out on the performance enhancement and design optimization of different configurations under variable operating conditions. Under the present paper, review of different rotor for the configurations of the cross‐flow hydrokinetic turbines are discussed. The paper will be useful to understand the cross‐flow hydrokinetic technology in order to explore the methods for selection, performance enhancement, and design optimization of cross‐flow hydrokinetic turbines.

As one of the best renewable energy sources, hydropower becomes more predictable source compared to wind energy and Savonius which its performance does not contingent to fluid flow direction. In this present, computational Fluid Dynamics acomplished by Finite Volume Method and unsteady RANS equation were applied to analyze the numerical simulation. The present study investigated the performance of Savonius Turbine by adding deflector plate installed to advancing blade side at 5, 10, 15, 30 and 45 of deflector angles in the direction of the fluid flow. The viscous turbulence model used realizable k-epsilon (RKE) and its descritization used second order upwind. The type of mesh was made from coarse to fine meshing with 8 (eight) types of meshing and the grid independency of the numerical simulation had been validated by the publish experimental data at TSR of 1,078. Grid independency occured at meshing G with the error lower than 5 % compared to published experimental data. The result of this study shows that the performance of Savonius turbine increased by adding deflector in advancing blade side with the maximum torque and power coefficient at 30 of deflector angle.
