In this study, the improvement of the turbine performance of Savonius, one of the vertical axis wind turbines, was carried out numerically. The numerical approach used in the improvement studies was supported by experimental results and was confirmed. Within the scope of this improvement, a wind collector was placed in the turbine front zone to decrease the negative moment on the counter-rotating blade of the Savonius turbine. To obtain the highest turbine performance, all of the changes in the design parameters of this wind collector, such as the wind inlet width, wind outlet width, collector length, and collector height, were examined, and ideal design parameters of the collector were specified. The geometric parameters of the investigated wind collector were taken depending on the circular dimension of the Savonius turbine used. Unsteady simulations for different geometric parameters using the sliding mesh approach were performed in the CFD program. According to the numerical analysis results, the power-coefficient of the conventional turbine was increased to 0.23 levels by using the wind collector with the ideal geometric parameters. Thus, with the use of a wind collector, the power coefficient of a conventional Savonius wind turbine was improved by about 54%.

“…After design, a simulation of the final design was done [14]. To analyse the efficiency of the VAWT turbine, design its own blade and simulate it, and to study some of the effect of some attack angle variables on the performance of the turbine at low wind speeds, the Qblade program was used [15][16]. The numerical simulation of the wind tunnel was conducted and the experimental analysis of the wind turbine from the rotor, the number of blades and the change in the length of the cord were studied.…”

The interest in green energy in recent years is very noticeable, as this energy is a very important alternative that can replace fuel in many applications, most notably electric power generation, so work must be done to develop a form of this energy such as wind energy by working on the development of turbines. The DMST method provided by Qblade software is an integrated tool for making a simulation of a vertical axis wind turbine (VAWT). The simulation was carried out on vertical axis wind turbines, designing turbine blades according to symmetrical NACA0018, and calculating some parameters such as power, torque and power coefficient. It is found that this type of turbine can be improved by treating the blade edges that contribute to the turbine power loss, thus improving the turbine at low wind speeds.
