“…Despite the fact that horizontal axis wind turbines (HAWTs) remain as commercially viable devices for large-scale onshore and offshore power generation, vertical axis wind turbines (VAWTs) have recently drawn fast-growing attentions for harvesting wind energy in low wind speed regions (Sranpat et al, 2017), urban environment (Bhargava et al, 2016) and some offshore fields (Cheng et al, 2016(Cheng et al, , 2017. This is mainly due to their simpler blade profile and shape, lower installation and maintenance costs, lower noise pollutions, lower operational tip speed ratio (TSR), and lower risk of wildlife damage (Ghasemian et al, 2017;Hui et al, 2018).…”

This article provides a comprehensive review about passive flow control devices (PFCDs) implemented in lift‐type vertical axis wind turbine (LVAWT), focusing on the underlying flow physics mechanisms and to what extents they can improve the LVAWT performance. In addition, some novel concepts that can be potentially implemented in future are also presented. Based on literature review, it is observed that PFCDs can enhance the power generation of LVAWT up to 172.73% compared with a clean LVAWT. However, this significant improvement still needs to be evaluated carefully by considering the economic feasibility aspect, because PCFDs can increase the design complexity, weight penalty and manufacturing cost of LVAWT. Furthermore, it is essential to design and evaluate the effectiveness of PFCDs using a full VAWT configuration by considering the blade rotating effects and blade‐to‐blade interactions. Finally, evaluation of PFCDs needs to be performed at all ranges of tip speed ratios (TSRs) operation conditions, as there are clear evidences on the correlation between LVAWT performance and different range of TSRs. This article is categorized under: Sustainable Energy > Wind Energy

“…Much research has been carried out so far in order to improve VAWT performance and to maximize the energy generation from the available wind power. In the case of Savonius type VAWT, this was done by considering alternate turbine designs such as twisting and/or modifying profiles of rotor blades [2][3][4][5][6][7], adding a fixed shielding plates, wind boosters or curtains (or ducts) around the entry of wind turbine to enhance wind power [8][9][10] as well as by increasing the number of rotor blades [11][12] or number of stages (i.e. multi step rotors) [13][14].…”

“…Augmentation of the power output of an H-Darrieus rotor by using a flat plate deflector was investigated by Wong et al, [16]. The effect of number of blades on the performance of VAWT was studied in references [11][12] and [17]. Furthermore, an attempt was made to design a hybrid turbine of Darrieus and a double/multi step Savonius turbine coupled on a single shaft and tested in different currents [14,[18][19].…”

To combine the advantages of performance of both Savonius and Darrieus wind turbines, this paper aims to study computationally a novel design configuration of a Vertical Axis Wind Turbine (VAWT). The new design would help cover a broad range of performance parameters between both types of wind turbines as well as overcome drawbacks of the Savonius type at higher rotational speed. The proposed design is to integrate both of Savonius and straight blade Darrieus wind turbines in a single VAWT design configuration. In this design, the turbine rotor consists of a number of similar NACA0015 airfoil blades set in a particular arrangement. By regulating individual angles of rotor blades, the turbine would work as either Savonius or H-Darrieus VAWT. The turbine could also be set to work at different configurations between those for the Savonius and H-Darrieus ones. The computational results revealed that the performance of the proposed integrating wind turbine would be controlled and optimized to cover the operating range of both of Savonius and Darrieus wind turbines. Besides, the performance of Savonius VAWT would be modified when applying this design. When the proposed design is practically implemented, characteristics of both of Savonius and H-Darrieus based wind turbines would be found in a single design.
