Wind turbines are spun from below too

Wind flowing from both above and below wind turbine blades can affect the supply of energy, researchers have discovered.

The study found that traditional ways of measuring the significance of wind flow changes have underestimated the energy potential of air flowing from below turbines.

Mathematical models developed in the research will assist in developing wind farms that draw more heavily on air flowing from below wind turbine blades.

The analysis will also be used in examining the differences in effectiveness between two-blade and three-blade turbines.
