This is the turbine we built here in May see www.scoraigwind.com It has 2 magnet rotors instead of using one magnet rotor with a plain disk on the outside. Air gap is large. Blades are coated with linseed oil as is tail vane. thanks to Lawrence Glass.

This video shows some output I generated when I simulated a Lenz2 turbine with the turbDyMFoam simulator of OpenFOAM. The partial revolution took about 20 hours for a 64 bit computer to calculate. Besides doing pictures and diagrams, the software can also calculate torques and forces so you can measure the power output of the simulated turbine. I still have much to learn about the use of this program. The wind in the simulation is 15MPH (6.7 m/s) in the +X direction. The turbine is moving with a TSR of 0.8. OpenFOAM is a free program, but its intended to run on Linux and is extremely complicated. I’m an Engineer and normally good with computers and it took a month of my free time to figure out how to install and use this program.
