Problem Description

The problem to be considered is shown schematically in Figure  1.1. A cold fluid at $20^{\circ}C$ flows into the pipe through a large inlet and mixes with a warmer fluid at $40^{\circ}C$ that enters through a smaller inlet located at the elbow. The pipe dimensions are in inches, but the fluid properties and boundary conditions are given in SI units. The Reynolds number for the flow at the larger inlet is 50,800, so the flow has been modeled as being turbulent.

Note:   This tutorial is derived from an existing ANSYS FLUENT case. The combination of SI and Imperial units is not typical, but follows an ANSYS FLUENT example.

Because the geometry of the mixing elbow is symmetric, only half of the elbow is modeled.
