This is a quick-and-dirty introduction to the basic concepts underlying CFD. The concepts
are illustrated by applying them to simple 1D model problems. We’ll invoke these
concepts while performing “case studies” in FLUENT. Happily for us, these model-problem
concepts extend to the more general situations in the case studies in most instances. Since
we’ll keep returning to these concepts while performing the FLUENT case studies, it’s worth
your time to understand and digest these concepts.
We discuss the following topics briefly. These topics are the minimum necessary to
perform and validate the FLUENT calculations to come later.
