Wind tunnel test compared with theory in Portugal

João P. Monteiro has done some interesting studies of the performance of a 1200 diameter Recipe blade set in a wind tunnel and compared the results with theoretical predictions of a couple of simulation progams.  The results are close.  It’s unusual to see real world data for the Cp (performance) versus tip-speed-ratio.  This can help us design wind turbines to avoid stall and maximise efficiency.

About hugh

I live off-grid in NW Scotland and have spent my life playing with wind turbines. I also love small hydros. Hands on renewable energy is my thing and I like to learn and to share my experiences.
