Title: Basic Concepts in Turbomachinery
Author: Grant Ingram
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.
