Problem Description

The problem to be considered is shown schematically in Figure  1.1. A cold fluid at 293.15 K flows into the pipe through a large inlet, and mixes with a warmer fluid at 313.15 K that enters through a smaller inlet located at the elbow. The pipe dimensions, the fluid properties and boundary conditions are given in SI units.

Note:   Since the geometry of the mixing elbow is symmetric, only half of the elbow needs to be modeled.
