Spinger has published a new book on combustion. It is based on the long-running undergraduate course at UC Berkeley ME140 Combustion Processes taught originally by Prof Carlos Fernandez-Pello (my former PhD supervisor):
Fundamentals of Combustion Processes 2011, Springer (Amazon $79.11)
The book is very accessible to engineering students interested in combustion but not advanced in their thermal science studies yet. There are few, or none, books for this introductory level. The accompanying dozen videos of laboratory demonstration act as a great illustration of each chapter content.
I am very familiar with the course and the labs, and I highly recommend the textbook for an introductory course. I was Teaching Assistant of this course for four semesters from 2002 to 2005. Such good memories, I loved it.
