Summary The use of different duct designs, aiming at increasing the wind speed and improving the performance of the wind turbine in low wind speed situations, has become of paramount significance over the past decades. In this research, the authors proposed a model to inspect the effect of increasing the suction behind the turbine using suction holes and increasing the air speed in front of the wind turbine using a conversion duct. A validated CFD model with multiple reference frame (MRF) approaches has been used to study four different configurations for a novel design for two circumferential converging ducts with suction holes at the inner duct to increase the extracted power from low‐speed air. The study tested ducts' dimensions in addition to the configurations and size of the suction holes at different tip speed ratios. Adding a baffle in front of the suction holes notably improves the duct's performance. The tested configurations for the proposed wind duct design with six suction holes resulted in a relative improvement in the Cp by 18.42% compared with the open wind turbine.
