By a News Reporter-Staff News Editor at Energy Weekly News -- Current study results on Energy have been published. According to news reporting from Anchorage, Alaska, by VerticalNews editors, the research stated, "In this study, a numerical model was developed to study the effects of aerodynamic interactions between a pair of counter-rotating vertical axis wind turbines (VAWTs) in close proximity. In this model, the rotor rotation is not prescribed as a constant as in most other studies, but is determined by the moment of inertia and the total torque of the rotor, including the aerodynamic torque, generator torque, and a torque representing friction."
The news correspondents obtained a quote from the research from the University of Alaska, "This model enables study of the behavior of the rotor under an arbitrary ambient wind profile. The model was applied to an isolated rotor with five straight J-blades and pairs of identical rotors placed in close proximity. Compared with an isolated rotor, the aerodynamic interactions between the pair of rotors enhance the aerodynamic torques on the rotors and significantly increase the turbine power output on a per unit basis."
According to the news reporters, the research concluded: "The enhancement in turbine power output due to aerodynamic enhancement decreases with the distance between the pair of rotors."
