Increase turbine output by tweaking ambient conditions

Daox · 09-08-09, 07:45 AM

I found this interesting. They using a deflector around the wind turbine to increase the volume of air going over the turbine. I wonder how effective it really is? From the CFD model it appears that it really does increase the speed across the blades.

Looks to me that it would increase the turbulence which might show up on an anemometer as increased wind speed, but the deflected wind would not be horizontal and would therefore not be beneficial for increased output of the generator. The basic rule of thumb is not changed by these deflectors--30 feet above anything within 500 feet. This system in the pictures needs a taller tower first.
