The previous blog, Entropy Happens… Deal with It! ended with the statement, “That’s how Concepts NREC deals with the constraints of the Second Law of Thermodynamics when designing high-efficiency turbomachinery – we literally put entropy to work!” That blog not only lead to an increase in sales of bumper sticker sales emblazoned with “Working on it, STAY TUNED!”, it led to a request to explore this statement in a little more detail – particularly as the idea might apply to the analysis, design and manufacturing of turbomachinery.
