“…Further, they can operate at low wind speeds causing lesser wear and tear, and their operation is independent of wind direction thereby avoiding the need of a yaw mechanism. [13,14,[16][17][18][19][20][21]. Looking at these advantages, it can clearly be said that if a higher efficiency can be achieved, these SSWTs would make an attractive source of power generation.…”

“…Kamoji et al [11] and Gupta et al [12] studied the aerodynamic characteristics of a modified Savonius turbine with helical blades, while Golecha et al [13] and Altan and Atilgan [14,15] placed a guide vane in front of the turbine to deflect flow for the returning blade. McTavish et al [16] proposed a modified blade shape and carried out both steady and transient CFD simulations.…”

Abstract:The Savonius wind turbine is a type of vertical axis wind turbine (VAWTs) that is simply composed of two or three arc-type blades which can generate power even under poor wind conditions. A modified Savonius wind turbine with novel blade shapes is introduced with the aim of increasing the power coefficient of the turbine. The effect of blade fullness, which is a main shape parameter of the blade, on the power production of a two-bladed Savonius wind turbine is investigated using transient computational fluid dynamics (CFD). Simulations are based on the Reynolds Averaged Navier-Stokes (RANS) equations with a renormalization group turbulent model. This numerical method is validated with existing experimental data and then utilized to quantify the performance of design variants. Results quantify the relationship between blade fullness and turbine performance with a blade fullness of 1 resulting in the highest coefficient of power, 0.2573. This power coefficient is 10.98% higher than a conventional Savonius turbine.

Golecha et al placed a guide vane in front of the turbine to deflect flow for the returning blade [21]. Kacprzak et al studied the performance of modified turbines with spline-type and Bach-type blades, and an increment of 16% in the efficiency was found in the case of using spline-type blades [22].…”

Abstract:Wind energy generated from the wake of moving cars has a large energy potential that has not yet been utilized. In this study, a vertical axis wind turbine (VAWT) was used to recover energy from the wakes of moving cars. The turbine was designed to be planted by the side of the car lane and driven by the wake produced by the car. Transient computational fluid dynamics (CFD) simulations were performed to evaluate the performance of the VAWT. The influence of two main factors on the performance of the VAWT, the velocity of the car and the gap between the car and the rotor, were studied. The simulations confirmed the feasibility of this plan, and in the tested cases, the VAWT was able to generate a maximum energy output of 100.49 J from the wake of a car. The results also showed that the performance of the VAWT decreased with the velocity of the car, and the increased gap between the car and the VAWT.
