“…HAWT has the advantage that it does not need external starting, which means that it is a self-starting machine, as well as the aerodynamic loads are fixed to a large extent, which facilitates handling and reduces their danger [32]. Many materials such as iron, aluminium, zinc, copper, titanium, nickel and fiberglass entering the turbine industry HAWT and VAWT as well as some natural biological compounds and thermoplastics are used in the manufacture of blades [33]. In fact, there are two main types of noise produced by wind turbines, which are tow mechanical, and aerodynamic noises.…”

Since ancient times, wind energy has been exploited in various fields, it was at the beginning used to rotate pumps for the purposes of agriculture and irrigation. At the beginning of the 18th century, wind turbines began to produce electricity with modest capacities. In the following years, the capacities of the turbines increased and it became necessary to deal with this increase by reducing losses and inventing new designs for turbines Suitable for working conditions and installation location. The rotor power coefficient in a wind turbine can reach 0.59 which is called the bets limit. The vertical axis wind turbine (VAWT) design was invented for working conditions, capacities, and places, in which it may be difficult to install older Horizontal axis wind turbines (HAWT). The efficiency of the HAWT is still higher than the VAWT, in addition, the amount of efficiency in the HAWT is greater than the VAWT by 25% but the VAWT has the amount of torque more than the HAWT. The main objective of this research is to compare the VAWT and the HAWT, taking into account several aspects which have been reviewed to try to understand the importance of the two designs.

“…Numerous studies examined diverse wind turbine parameters, such as alternative blade designs [20][21][22][23], and the minimum and maximum wake loss and output power production, respectively [24,25]. Researchers have also attempted to determine how the efficiency is impacted by various internal and external forces [26,27], and how the overall wind turbine performance is affected by ice, sand, and blade roughness. Other studies have examined the effect of the hub and tower in the context of the wake flow [28][29][30][31][32].…”

In order to construct a 3D rotor model, periodicity and Multiple Reference Frame (MRF) strategies were applied to address full Computational Fluid Dynamics (CFD) that incorporate the Reynolds-averaged Navier-Stokes (RANS) equations. A simulation model was run to examine the power of the wind turbines, both including and excluding the hub and tower. The purpose of this was to identify an approach that would decrease the computational time cost of wind turbine simulation. Firstly, a full-scale horizontal axis wind turbine simulation was carried out, and subsequently, comparisons were made with the results of the wind tunnel experiment utilizing the K-omega SST and Sparlat Allmaras viscosity models. The results were compared to determine the optimum model with the lowest simulation time and highest accuracy to the experimental results. Following this, the complete models' simulation was compared to the model excluding the hub and tower in order to check the disparity in the results of the two. Additionally, to ascertain the computational cost saving, the ratio of the two simulation times was established. The findings show that the two models produce results that correspond well to the experimental results, and that the power coefficient had a greater value for the complete model than the simple model. Furthermore, it was found that the power coefficient values of the full model have significantly higher levels of similarity to the experimental values. The Sparlat Allmaras and K-omega SST viscosity models returned error percentages of 0.52% and 12.6% respectively. For the partial model utilizing the same computer device, a 5.7% error rate was recorded, with a computational time saving of approximately 34%.

“…Changes in geometry are still the primary research to improve turbine performance, such as PSA [13], Aspect Ratio [14], Number of blades [8,15], Overlap ratio [16], Number of stages [6], and shape of blade [3]. However, apart from the geometric aspect, several other factors also influence, such as the rotor material factor [17][18][19][20].…”

Hydropower is a renewable energy source with a lot of potential in Southeast Asian countries, with a total energy potential of 152,257 MW in Southeast Asia. The development of a hydro-turbine design is required due to the enormous hydropower potential. The turbine's runner is critical for converting fluid internal energy into kinetic energy. A cross-flow turbine that has gained popularity recently is the banki-turbine. The research that has been done is three-dimensional modeling of the banki-turbine with the CFD method. This study aims to determine the effect of the blade's angle on turbine performance. This research's steps are design, mesh independence, validation, simulation, and analysis. Modeling research was conducted with variations of blade angles 10˚, 15˚, and 20˚. Schematic modeling using a steady state condition, the turbulent type Shear Stress transport (SST), and the tetrahedral mesh method. The modeling consists of a rotating zone and a stationary zone. The water inlet velocity is 3 m/s, and the outlet pressure equals the room pressure (1 atm). Simulation of bankiturbine operated in 50 RPM until 350 RPM of angular velocity. One of the analyzes used is Factorial Design. The best performance Cpmax is obtained from the variation of the blade's angle of 15˚ on 0.28.
