6 FAQs about [Pre-buried wind tunnel for wind power generation]

Can a tunnel-based wind turbine produce more power than a traditional wind turbine?

SheerWind, a US wind energy company, has announced that their innovative INVELOX tunnel-based wind turbine system has proven that it is capable of producing 600% more power than traditional wind turbines.

Should wind turbine experiments be conducted in wind tunnels?

Wind turbine (WT) experiments in wind tunnels can benefit the efficient utilization of wind energy in many aspects, such as the testing of new products, the validation of numerical models, and the exploration of underlying mechanisms of WT-induced flow field. However, there is a lack of comprehensive and critical review on this topic.

What is NTNU wind tunnel?

Measurements at NTNU A large low-speed, closed-circuit wind tunnel, which has a test section of 12 m (length) × 2.7 m (width) × 2 m (height) is located at the Norwegian University of Science and Technology (NTNU) to accommodate model turbines with a diameter of 0.9 m.

What are the research challenges and prospects in wind tunnels?

Research challenges and prospects are summarized. Wind turbine (WT) experiments in wind tunnels can benefit the efficient utilization of wind energy in many aspects, such as the testing of new products, the validation of numerical models, and the exploration of underlying mechanisms of WT-induced flow field.

Does a wind tunnel have a blockage ratio?

The wind tunnel is equipped with a 220 kW fan to provide incoming wind speeds up to 30 m/s. Although the blockage ratio is a little bit larger than 10%, no correction was adopted for simplicity. Adaramola and Krogstad conducted a series of tests for both isolated wind turbine models and multiple wind turbines.

Can a wind tunnel model be fixed with embedded parts?

According to the authors’ experience, it is feasible to fix the terrain model on tunnel floor with embedded parts. At last, since the existing algorithms are unable to accurately predict the flow features caused by complex terrains, this kind of wind tunnel experiment can be used to develop a more advanced prediction model.
