Description A senior level undergraduate and graduate textbook for a wide audience of engineering students taking a first course in CFD or Computer
Aided Engineering. Fully course matched, with the most extensive and rigorous pedagogy and features of any book in the field. The first
book in the field aimed at CFD users rather than developers.
Audience
Senior level undergraduate and graduate students of mechanical, aerospace, civil, chemical, environmental and marine engineering. Beginner
users of commercial CFD software tools (including CFX and FLUENT)
