The truncated-cone-shaped wind gathering device proposed in this study was proved to be effective for both the static toque characteristics and output power performance improvement of straight-bladed vertical axis wind turbine based on numerical simulations and wind tunnel tests.
The results also show that the QORCD method can be used for the study on straight-bladed vertical axis wind turbine with wind gathering device. The wind gathering device can effectively improve the rotational speed performance and output power characteristics especially at the low wind speeds based on the wind tunnel test results.
Scientific Reports 15, Article number: 6921 (2025) Cite this article Co-rotating, counter, and contra-rotating Vertical Axis Wind Turbines (VAWTs) offer higher power yields than singular turbines due to synergetic interactions, making them ideal for rooftop applications.
Wind power plays a pivotal role in this debate. Wind power is a “form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power,” according to Noelle Eckley Selin of the Massachusetts Institute of Technology. As Selin notes,
