Offshore wind turbines operating in frigid and humid climates may encounter icing on the blade surface. This phenomenon adversely impacts the aerodynamic efficiency of the turbine, consequently diminishing power generation efficacy. Investigating the distribution characteristics of icing on the blade surface is imperative. Hence, this study undertook icing wind tunnel tests on segments of DU25 airfoil, a prevalent type for offshore wind turbines, to examine such characteristics as different chord lengths and angles of attack. The results show a simultaneous increase in the blade icing area and growth rate of the net icing area with augmenting the chord length and angles of attack. The total icing area rate decreases by a factor of two when the chord length is doubled. The relative positioning of icing and the average icing thickness remain consistent across the airfoil blades with varying chord lengths. Comparing the icing shapes on blades of varying scales shows a similarity ranging from 84.06% to 88.72%. The results of this study provide insight into the icing characteristics of offshore wind turbines.

“…In the process of clean energy research, wind energy resources with clean, pollution-free, and renewable characteristics have attracted increasing attention in recent years [2,3]. According to their different rotational shaft arrangements, wind energy capture machinery can be divided into horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs) [4][5][6][7][8]. Until now, the HAWT has been the main model in the wind turbine market due to its higher efficiency in capturing wind energy.…”

In order to improve the energy capture performance of vertical axis lift wind turbines in a low wind speed environment, the drag wind turbine is employed to couple with the design of existing vertical axis lift wind turbines. In contrast to the existing literature, in this work, a computational model is proposed that can simulate the interaction between the turbine and the fluid. The effects of pitch angle (β), installation angle (θ), overlap ratio (ε) and diameter ratio (DL) on the energy capture performance of hybrid vertical axis wind turbines are systematically analyzed based on Taguchi and CFD methods. The results show that under the optimized parameter combination, the peak energy capture coefficient of the lift-drag hybrid wind turbine can be increased to 0.2328, compared with 0.0309 and 0.0287 of the pure lift and drag turbine, respectively. In addition, the result of the prototype test show that the optimized hybrid wind turbine not only has a better-starting performance but also has 2.0 times the output power of that of the lift wind turbine.

“…HAWTs are commonly used in large wind farms and offshore wind farms due to their larger application scales and more mature research (Eltayesh et al, 2021;Bošnjaković et al, 2022). On the other hand, VAWTs face more difficult research problems due to their blades cutting the flow field back and forth, a wide range of changes in angle of attack (AOA), and complex aerodynamics in one rotation cycle (Zhang and Hu, 2020;Li et al, 2023). However, VAWTs have several advantages over HAWTs, such as not requiring yawing into the wind, having a low center of equipment gravity, being simple in structure, low in cost, low aerodynamic noise, easy to install and maintain, and having high safety (Guo et al, 2022;Ni et al, 2022;Pietrykowski et al, 2023).…”

“…VAWTs, especially straight-bladed VAWTs (SB-VAWTs), a Darrieus type VAWT, are ideal for utilization of wind energy on board ships due to their lower complexity, ease of operation, lower costs, and superior ship stability. SB-VAWT is one of the most investigated VAWTs in the world due to their regular blade shape, ease of fabrication, low cost, and great aerodynamic characteristics (Wang et al, 2018;Guevara et al, 2021;Li et al, 2023). Figure 1 illustrates practical applications of SB-VAWTs on ships (Hand and Cashman, 2020;Zhang and Hu, 2020).…”

“…VAWTs are now designed with intermediate support shafts and struts (Li et al, 2023;Wilberforce and Alaswad, 2023), which are regarded as critical components that must not be disregarded when bearing loads (Li et al, 2015). Several studies have been conducted to investigate the impact of these support structures on the VAWTs' aerodynamic performance.…”

Wind power generation is considered an effective way for ships to harness wind energy, and the aerodynamic characteristics of wind turbines determine wind energy utilization and efficiency. However, traditional vertical axis wind turbines have intermediate shafts and support rods, which result in large negative effects in the research of the wind turbine aerodynamic characteristics. To address this issue, a Straight-Bladed Vertical Axis Wind Turbine (SB-VAWT) without intermediate support axes is proposed. The turbine can flexibly change the number of blades, rotor diameter, and installation position of blades. The static aerodynamic performance of the wind turbine with different combinations was tested in a wind tunnel laboratory at 10 m/s. The results show that the radius of the wind turbine has a greater effect on the drag coefficient for the same number of blades, with an inverse relationship between the drag coefficient and radius, and a positive association between lift coefficient, static torque coefficient, and radius. The drag coefficient is proportional to the number of blades at the same radius, while the static torque coefficient is inversely proportional to the number of blades. According to the results, placing the initial location in the azimuth range between 30° and 50° can obtain the maximum initial starting torque. Moreover, a wind turbine with a radius of 16 cm can achieve a higher average torque. Changes in the number of blades can significantly impact turbine properties, resulting in wind turbines with distinct features.
