Quad Wind Turbine Array-Breakthrough in Wind Resource Utilization
Greenward Technologies Announces a Major Breakthrough in Wind Resource Utilization Using Their 'Quad Wind Turbine Array. Greenward Technologies, Inc. announced today that data from controlled velocity testing of their scale model counter-rotating quad wind turbine array strongly supports the Company's 'Wake Convergence plus Swirl Cancellation' hypothesis.
Single flow channel at about 2 ½ to 3 rotor diameters downstream, then fully restoring to free stream velocity at just under 5 rotor diameters. This really got our attention, particularly in view of the fact that the CFD study did not consider the effect of counter-rotating swirl. If the turbine wakes can be made to converge quickly, then it is a virtual physical requirement that the opposing swirls will sum to zero, or cancel each other'.
