For the wind turbine the value of flo may not be small compared with 1 and so the above procedure will converge on values of ao which are too small compared with what the momentum theory would deliver.

To produce more realistic results that is, results in line with Glauert's momentum theory where

CT = 4a\J 1 — a(2cos y — a) = 4aAG(a) or the Coleman theory, where

CT = 4a ( cos y + tan ^ sin y — a sec2 ^ J = 4aAC(a)

Also, the wake skew angle should be used in matrix [ L] instead of the yaw angle. The matrix [ L] should then be modified to become

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
