- Abstract
This research study conducts a numerical analysis of torque in modified turbines with vortex generators (VGs) by using computational fluid dynamics (CFD) simulations in 3D. Simulated torques are obtained for angular inclination variations of vortex generators located in the blades' extra-backs. This is performed at two different air temperatures. The results show that the maximum torque is at 10°C at a 30° vortex generator inclination angle, with a value of 8.5 Nm. The minimum torque is observed at 25°C with a 45° inclination angle, having a value of 4.2 Nm. In conclusion, the CFD simulation shows that at higher air temperature the lower the torque in the turbine, reducing the rotational mechanical power, and that vortex generators reduce turbulence kinetic energy (TKE) in the generated wind wake.
