The book is
designed to help students over some important “Threshold Concepts” in
educational jargon. A threshold concept is an idea that is hard to grasp but
once the idea is understood transforms the student understanding and is very
hard to go back across. Within turbomachinery my view is that understanding the
cascade view, velocity triangles and reaction form three threshold concepts, perhaps
minor ones compared to the much bigger ideas such as “reactive power” or
“opportunity cost” that are also proposed but this view has significantly
influenced the production of this book. I’d therefore like to acknowledge
Professor Eric Meyer for introducing me to the idea of threshold concepts.
