A Numerical Study of INVELOX Wind Turbine Considering the Inlet Shape Design

Increasing efficiency in wind turbines has remained a concern in this industry. By introducing duct turbines, researchers tried to improve the power output. The INVELOX wind turbine is a new system designed to produce more energy by getting the wind from all directions, steering the wind to the Nozzle, and then turbine in the lower side to gain more velocity. In this article, by using the CFD tools, many geometrical parameters in the inlet section have been investigated, affecting the performance of the turbine. The results show that by increasing the height and diameter of the inlet area two times, the power output will be increased up to 35% compared to the original design.
