ABSTRAKKarakteristik blade sisi cekung turbin hidrokinetik Savonius yang memiliki nilai torsi negatif mengakibatkan kelemahan berupa efisiensi turbin yang relatif rendah, sehingga diperlukan sistem pengarah aliran berupa rectifier guide vane. Studi ini bertujuan membandingkan performa yang dihasilkan turbin Savonius tanpa guide vanes dan turbin Savonius menggunakan guide vanes dengan memvariasikan lebar rectifier L=Rt/4, L=Rt/2 dan L=3Rt/4, dimana Rt adalah jari-jari turbin. Metode pengujian dilakukan secara eksperimental di saluran prismatik dengan kecepatan aliran 0,111–0,1415 m/s. Hasil studi menunjukkan bahwa penambahan guide vanes dengan variasi lebar rectifier L=Rt/4, L=Rt/2 dan L=3Rt/4 masing-masing menghasilkan peningkatan torsi sebesar 29,9%; 33,3%; dan 36,3%. Turbin Savonius menggunakan guide vanes dengan lebar rectifier L=3Rt/4 menghasilkan coefficient of torque (Ct) dan coefficient of power (Cp) yang lebih tinggi dibandingkan variasi lebar rectifier (L) lainnya, sehingga kinerja turbin meningkat.Kata kunci: coefficient of power, hidrokinetik, savonius, rectifier guide vanes ABSTRACTThe characteristic of the concave side blade of the Savonius hydrokinetic turbine which has a negative torque value, it leads to the weakness in the form of a relatively low turbine efficiency, thus a flow steering system is needed in the form of a rectifier guide vane. The aim of this study was to compare the performance of the Savonius turbine without guide vanes and the Savonius turbine using guide vanes by varying the width of the rectifier L=Rt/4, L=Rt/2 dan L=3Rt/4, where Rt is the turbine radius. The test method was undertaken experimentally in a prismatic channel with a flow velocity of 0.111–0.1415 m/s. The results of the study pointed out that the addition of guide vanes with variations in the width of the rectifier was L=Rt/4, L=Rt/2 dan L=3Rt/4 and each of them had an increase in torque of 29.9%, 33.3% and 36.3%. The Savonius turbine used guide vanes with a rectifier width of L=3Rt/4 and it resulted a higher coefficient of torque (Ct) and coefficient of power (Cp) compared to other variations of rectifier width (L), thus, the performance of turbine increased.Keywords: coefficient of power, hydrokinetic, savonius, rectifier guide vanes

Abstract:
Energy consumption has become a primary commodity due to technological revolutions in developing countries, such as the expansion of the hydrokinetic turbine as a renewable energy source to mitigate environmental issues. However, conventional vertical axis turbines in hydrokinetic applications particularly for small rivers with low speeds, have limited capabilities such as great power but poor self-start or vice versa. Therefore, the current study aims to address this issue by investigating a hybrid turbine through quantitative and qualitative wind tunnel experiments to improve the performance and self-start capability by integrating Savonius and Darrieus turbines. The findings discovered that the maximum torque coefficient of the hybrid turbine is 37% higher than that of a single conventional Savonius turbine. The integration of the hybrid turbine has resulted in a higher torque coefficient which has enhanced the self-start performance. The hybrid turbine achieved a maximum power output improvement of 30% at a low Reynolds number of 89500, typically representing the small river flow conditions. The presence of a substantial wake captured by the smoke generator at the rear part of the hybrid turbine signifies large drag resulting in power loss and a subsequent decrement in power output. The hybrid turbine has demonstrated its potential to be implemented in hydrokinetic applications in developing countries such as Malaysia for sustainable energy generation.

Abstract:
Hydropower is at present in many locations, among all the other possible renewable energy sources, the best one for net cost per unit power. In contrast to traditional installation, based on water storage in artificial basins, free flow river turbines also provide a very low environmental impact due to their negligible effect on solid transport. Among them, kinetic turbines with vertical axis are very inexpensive and have almost zero impact on fish and local fauna. In application to tidal waves and sea waves, where vertically averaged velocities have alternate direction, a Savonius rotor also has the advantage of being productive during the whole time cycle. In this work, the effect of an upstream deflector system mounted upstream of a twisted Savonius rotor inside a channel has been investigated through numerical simulations and experimental tests. Numerical simulations were carried on using the ANSYS FLUENT 17.0 software. Based on this numerical study, it is shown that the proposed deflector system has improved the power coefficient of the Savonius rotor by 14%. The utilization of this new design system is predicted to contribute towards a more efficient use of flows in rivers and channels for electricity production in rural areas.

Abstract:
The Savonius turbine is practical in generating off-grid electrical power for hydrokinetic applications due to its simple design, particularly for small rivers in rural areas. However, despite many studies on methods to improve turbine performance, the electrical aspect of the turbine system is rarely discussed. Therefore, the present study aims to evaluate the performance of a simple and affordable power storage system using a conventional 2-bladed Savonius turbine. The experiment was conducted in a wind tunnel and a water channel with flow speeds of 6 m/s and 0.33 m/s, respectively, corresponding to a Reynolds number of 62700. A power coefficient of 0.09 was discovered for the wind experiment and 0.11 for the water. The total amount of energy extracted from the water was 60% less than from the wind due to the lower available power. It was observed that the tip speed ratio decreases over the charging period due to the constant current and voltage of the Lithium-Ion batteries. This will allow for a fluctuation in the amount of required current and consequently affect the torque needed to spin the generator. The findings confirmed the functionality of the electrical storage system and contributed to the low manufacturing and maintenance cost of the hydrokinetic turbines.

Variasi tiga blade dan enam blade, dengan diameter turbin 0.44 m x 0.15 m pada turbin luar dan 0.18 x 0.14 m pada turbin bagian dalam, panjang chord 0.10 m dengan variasi sudut serang 0º sampai dengan 360º, variasi kecepatan air pertama 0.3 m/s, variasi kecepatan aliran air kedua 0.65 m/s. Kecepatan air 0.3 m/s enam blade, torsi statik 0.3 Nm, torsi dinamik nya 0.384 Nm, kecepatan air 0,65 m/s torsi dinamik 0.432 Nm dan torsi statik nya 0.384 Nm, pengujian turbin Darrieus tiga blade kecepatan air 0,3 m/s nilai torsi dinamik 0.336 Nm dan dengan kecepatan yang sama torsi statik nya 0.264 Nm. Pada kecepatan air 0.65 m/s nilai torsi dinamik sebesar 0.384 Nm, dan nilai torsi statik 0.336 Nm. Dari data hasil pengukuran tersebut dapat disimpulkan bahwa variasi turbin enam blade memiliki nilai torsi statik dan torsi dinamik yang lebih tinggi dari pada turbin tiga blade, jumlah blade sangat berpengaruh terhadap daya serap energi kinetik air untuk di konversikan menjadi torsi statik maupun torsi dinamik.Kata kunci : Turbin Hydrokinetic, Darrieus, Torsi Statik,Torsi DinamikAn experimental study of the H-type Darrieus water turbine was carried out using a standard NACA 2415 hydrofoil blade to determine the value of static and dynamic torque generated by the 3-blade and 6-blade Darrieus H-type water turbine, testing using a water tunnel dimensions of 6m x 0.6m x 1m. Variation of three blades and six blades, with a turbine diameter of 0.44 mx 0.15 m on the outer turbine and 0.18 x 0.14 m on the inner turbine, chord length 0.10 m with variations in angle of attack 0º to 360º, variation of first water velocity 0.3 m / s second water flow velocity 0.65 m / s. Water velocity 0.3 m / s six blades, static torque 0.3 Nm, dynamic torque 0.384 Nm, water velocity 0.65 m / s dynamic torque 0.432 Nm and static torque 0.384 Nm, Darrieus three blade turbine test water speed 0.3 m / s dynamic torque value of 0.336 Nm and with the same speed its static torque is 0.264 Nm. At 0.65 m / s water velocity, the dynamic torque value is 0.384 Nm, and the static torque value is 0.336 Nm. From the measurement data, it can be concluded that the six-blade turbine variation has a higher value of static torque and dynamic torque than the three-blade turbine, the number of blades greatly influences the absorption of water kinetic energy to be converted into static torque and dynamic torque.

Abstract:
Darrieus rotor is a promising technology for hydrokinetic and wind energy harvesting applications. However, the Darrieus rotor suffers from the problem of poor starting performance. The present research highlights solutions to improve the poor starting performance of the Darrieus rotor by introducing the hybrid rotor. Further, a comparative performance evaluation of conventional vertical axis Darrieus and hybrid rotors has been investigated numerically. The most widely used S-series S-1046 hydrofoil has been utilized by hybrid and Darrieus rotors. Further, two semicircular blades are used for the Savonius part of the hybrid rotor. The size of the Savonius part is optimized to obtain maximum performance from the hybrid rotor. Analyzing the flow field distributions across the turbine vicinity has highlighted various possible reasons. The study results have demonstrated that the hybrid rotor yields an exceptional increment of about 159.41% in the torque coefficient under low tip speed ratio (TSR) regimes (during initial starting) compared to the Darrieus rotor. However, due to the Savonius rotor's presence, the hybrid rotor's maximum power coefficient is reduced slightly compared to the maximum operating point of the Darrieus rotor. Further, the hybrid rotor yields a wider operating range than the single maximum operating point by the Darrieus rotor. The present investigations will assist the designers in selecting the site-specific hydrokinetic technology suitable for efficient and optimum use of hydrokinetic potential.

Abstract:
The crossflow type Savonius turbine is capable to rotate at low current velocity conditions. The drawback of this turbine lies on its efficiency. This study aims to test its performance before implementation in the field. The research method used is an in-situ experimental study in Umbulan, Pasuruan. Turbine model T1 AR 1.145 without deflector is used, when TSR reaches a value of 0.824, it gets a CQ value of 0.327 and a CP value of 0.269. In the same model with deflector, when TSR reaches a value of 1.1, the CQ value is 0.251, and the CP value is 0.276. It can be concluded that this turbine is suitable for area with low current velocity.

Abstract:
Hydrokinetic energy is the energy of a water mass due to its flow. The greater the water velocity, the greater is the hydrokinetic energy it posesses. Hydrokinetic turbines are used to covert this kinetic energy to obtain electricity. Since the performance of these turbines played an important role in viability of hydrokinetic power generation projects hence different design parameters are studied to enhance its power generation capacity and performance. In this project torque and rotational speed of simple Savonius turbine are obtained at different speeds. The values of stream velocity are taken as 0.8m/s and 2.0 m/s for 2Dtransient analysis where variation of speed with time is studied. Diameter of the blade is taken as 0.266m and height of the blade is taken as 0.17m. For 3D-steady analysis stream velocities are taken as 0.3m/s, 0.65m/s and 0.9 m/s. The design of turbine blade is done on Solid Works, domain of the blade and meshing is done on ICEM CFD. CFD analysis is done with the help of ANSYS FLUENT. Using transient setup, a plot between time and rpm is plotted.

Abstract:
Savonius Hydrokinetic Turbine (SHT) is a small-scale renewable energy source that is a sustainable solution for remote areas and rural electrification. The current research work establishes a numerical study on combined effect of deflector plate (no deflector, deflector at 90°, deflector at 45°), twist angle of blades (0°, 12.5°, 25°), and tip speed ratio (0.5 to 1.5) on the turbine efficiency in terms of power coefficient (Cp) using CFD simulation considering a realizable k-ε turbulence model. A total of 99 simulations were performed considering all the above different conditions. To validate the results, simulations were compared with the results of a previous study having no deflector plate. It has been identified that SHT with blade twist angle of 12.5° and deflector plate at 90° produces highest power coefficient as 0.364 at tip speed ratio of 0.9 and 0.5 m/s water velocity. Similarly, SHT having a blade twist angle of 25° with deflector plate at 90° yields the highest torque coefficient as 0.454 at a TSR of 0.5. It was observed that Cp increases by an average 15% for SHT having blade twist and deflector plate as compared to SHT without blade twist and deflector plate.

Abstract:
The rise in energy demand, climate change and depletion of fossil fuel, encourages the researchers to find a solution to the scarcity of clean energy. Therefore, the extraction of energy from renewable energy sources has become a topic of interest in the past few decades across the globe. Thus, harvesting the offshore wind and hydro energy and converting it to electrical power using various electromechanical devices has been a challenge. In this context, the vertical-axis Savonius wind and Savonius hydrokinetic turbines appear to be promising concept for energy conversion because of their good self-starting capability and simplicity in design. The present study attempts to characterize the performances of a Savonius wind turbine (SWT) and a Savonius hydrokinetic turbine (SHT) under identical input flow conditions. In order to characterize their performances, the SWT is tested in a low-speed wind tunnel with closed test section whereas the SHT is tested in an open channel flume. In each case, the torque and power coefficients are estimated at different mechanical loading conditions. It is observed that the SWT and SHT demonstrate peak power coefficients of 0.25 and 0.28 respectively for the same input power. However, the SWT is found to operate over a slightly wider range of tip-speed ratios than the SHT before the onset of stall. Finally, the computational study using ANSYS 14.5 has been carried out to evaluate the flow physics of the turbine at various azimuthal positions.
