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

As shown in the following figure, vortices are shed from the rear of a bluff cylinder placed across a flow. The vortices alternately leave the top and bottom of the cylinder, causing an alternating force normal to the freestream velocity. The vortex shedding frequency, f, depends on the fluid density p, width of the cylinder d, freestream velocity V, and fluid viscosity u. (a) Use Buckingham Pi Theorem to develop a functional relationship for f. Use M, L, t as the primary dimensional. Use p, V, and d as the repeating parameters. (b) Vortex shedding occurs in standard air on two cylinders with a diameter ratio of 2. Determine the velocity ratio for dynamic similarity, and the ratio of vortex shedding frequencies. -Vortices V
