Chapter 15, Problem 15-7C(choose chapter or problem)
Suppose you are using CFD to simulate flow through a duct in which there is a circular cylinder as in Fig. P157C. The duct is long, but to save computer resources you choose a computational domain in the vicinity of the cylinder only. Explain why the downstream edge of the computational domain should be further from the cylinder than the upstream edge.
