Large wind turbines of the horizontal axis are commonly used to gather energy; however, their performance is found be constrained in conditions erratic and low-speed flow. In contrast, low conditions—which typically present dense urban areas—are favour vertical (VAWT). These have a simple design, inexpensive quiet, discovered better situations. this research, we chosen tree applications absorb ...

Abstract In this work, the performance of Savonius vertical axis wind turbine with secondary blades was investigated numerically. The impacts two geometric parameters blades, including height (h) and distance between main (b) on output torque were analyzed. Numerical simulations performed by a commercial CFD code, ANSYS FLUENT 18.2. results show that employing has constructive impact compared t...
