Chapter 15, Problem 46CP

Gerry creates the computational domain sketched in Fig. P1 5-46C to simulate flow through a sudden contraction in a two-dimensional duct. He is interested tithe time-averaged pressure drop and the minor loss coefficient created by the sudden contraction. Gerry generates a grid and calculates the flow with a CFD code, assuming stead, turbulent. incompressible flow (with a turbulence model).
(a) Discuss one way that Gerry could improve his computational domain and grid so that be would get the some results in approximate) half the computer time.
(b) There may be a fundamental flaw in how Germ’ has set up his computational domain. What is ir? Discuss what should be different about Gerry’s setup. Chapter 15, Problem 46CP, Gerry creates the computational domain sketched in Fig. P1 5-46C to simulate flow through a sudden FIGURE P15-46C
