“…The highest power coefficient value is precisely generated in a configuration in some variations of the different blades. The test results also showed that the more significant number of blades turbine and GV blades led to the design higher power coefficient in the turbine configuration (Andreas et al 2018). Therefore, the turbine has 22 blades with 14 GV producing a higher maximum power Coefficient than the turbine with 14 blades with 14 GV blades.…”

A cross-flow wind turbine has a high torque coefficient at a low tip speed ratio; therefore, it is a good candidate for a selfstarting turbine. This study aims to investigate the best configuration between guide vanes and cross-flow vertical axis wind turbine. The experiment test was carried out to determine the turbine with the highest power coefficient. The cross-flow turbine has 14, 18, and 22 blades with using 6,10 and 14 blades of guide vane (GV) was developed in this study, employing 15°, 25°, 35°, 45°, 55°, 65°, and 75° of tilt angles in fifth different wind speed conditions 4 m/s, 6 m/s, 7.5 m/s, 9.20 m/s, and 11 m/s. The turbine has 22 blades with 14 GV blades at 55° of tilt angle blades producing more remarkable turbine performance improvement than other blades. The highest power coefficient (CP) of cross-flow using 14 GV blades at 55° was 0.0162 at 0.289 TSR, which increased around 59% of the turbine's performance using GV.Keywords Cross-flow wind turbines • Guide vanes (GV) • Tilt angles • Power coefficient (CP)

“…Their results indicate that this number can vary depending on various conditions, such as the direction of rotation, type of installation (VAWT or HAWT), blade shapes, wind velocity, and Reynolds number. In most studies, 12 [104][105][106] and 16 [107][108][109] blades were recommended that can lead to the highest performance. However, other studies determined that 7 [110], 18 [111], 20 [112,113], and 22 [114,115] blades were the best choices.…”

The rapid globalization of the energy crisis and the adverse effects of global warming have caused the need for non-conventional energy resources to be felt more than ever. As a result of this, vertical axis wind turbines (VAWT) have received much attention over the recent decades, and have thus been more developed and used worldwide. The cross-flow wind turbine (CFWT) is a wind turbine in the category of VAWTs, and perfectly suitable for urban applications due to its simplicity, high starting torque at low wind speed, and self-starting capability, even though its low power coefficient as its main drawback has slowed down its widespread use so far. The main aim of this paper is to review the scientific literature and recent developments in the field of CFWTs. The governing equations and turbulence models for the simulation of the turbine are discussed and various wind resource assessment methods for estimating potential site locations, different aspects, and wind energy harvesting systems from buildings are debated. The research gaps, challenges, and future possible works on such turbines and their applications are discussed. Investigations indicate that changing the rotor geometric parameters and adding innovative augmentation devices have been the most widely addressed approaches for making performance enhancement of the wind turbine in the literature. The critical performance-affecting parameters are improved by various innovative designs of the turbine structure or blades, as well as several augmentation techniques, such as guide nozzle, casing, windshield, guide vane, deflector, cowling, etc.

“…Andreas Wibowo et al [2] The primary purpose of this investigation is to determine the ideal configuration between both the aide balancing and the cross-stream vertical pivot wind turbine, taking into account a range of variables such as the aide balancing' point of ability and the number of turbine sharp corners and guiding vanes. In comparison to the basic structure excluding the structure of a guide vane, the results indicated that with a specific setup, the aide vane may significantly increase the force generated by the wind turbine by 271.39 percent.…”

The use of wind based energy is quickly expanding over the planet. The goal of this study is to use computational methods of fluid dynamics to develop a novel model of VAWT including Windbooster for various rotor blades like two, three, and four blades in order to enhance effectiveness. CAD modelling approaches of vertical axis wind turbines including and excluding booster are created. Including all vertical axis wind turbine blade designs including and excluding booster, torque, power, and Coefficient of performance are compared.The performance of three blades on the basis of mechanical properties includingi wind amplifier is 29.9% greater than two blades using wind amplifier, and four blades using wind amplifier is 21.5 percent greater than three blades using wind amplifier, according to the findings. Because the mechanical energy created by a four-blade wind booster wasn't as great as it is including three blades, VAWT employing three-blade wind booster seems to be more effective than VAWT with a two- or four-blade wind booster. For improved mechanical durability, VAWT with three-blade wind amplifier is recommended.
