Abstract

Today, many efforts have been done to extract power from wind energy and increase the efficiency of wind turbines. The energy extraction started with blade rotation in wind turbines. Ducted wind turbines are turbines in which the airflow is directed towards the turbine blades using a built-in duct. The Invelox wind turbine is one of the ducted wind turbines, which directs the airflow towards the throat of the duct where the turbine is. In this research, an experimental study has been conducted on the Invelox wind turbine to improve the performance and efficiency of the turbine’s duct. Also, to check the performance of the Invelox wind turbine’s duct, the effect of placing a surface roughness in the inlet of the duct has been investigated for flow control. According to this research, adding a suitable roughness in invelox leads to a 7% increase in the local velocity at the throat of the invelox wind turbine. This leads to an increase in the efficiency of the invelox duct and increases the rate of energy extraction from the turbine.
