Researchers at Aarhus University in Denmark and Durham University in the U.K. used computer modeling of fluid dynamics to determine that wind turbines with four rotors on one foundation have advantages over other designs.

The researchers found that turbulence in the wake of the turbines recovers much faster with multi-rotor turbines, so a turbine downwind will produce more energy and will be subjected to less load and stress, because the turbulence is correspondingly smaller.

The researchers also found that multi-rotor turbines produce about 2% more energy than single-rotor turbines.

Said Aarhus researcher Mahdi Abkar, "We've explored several different geometries and dynamics of multi-rotor turbines and have found that the optimum construction is a turbine with four rotors as far apart as possible."
