The mixing elbow is the classic introduction to Fluent because it is small enough to solve quickly while containing real physics: two streams at different temperatures meet at a junction, mix, and leave through a common outlet.
Running it steady and then unsteady shows what each formulation gives you. The steady run produces the final mixed state, which is what you need for an average outlet temperature. The transient run shows how the mixing layer oscillates and how long it takes to settle, which matters for thermal fatigue at the junction.
The transient case only makes sense if the time step resolves the motion. A step so large that a fluid particle crosses several cells per iteration smooths away the very fluctuation you were looking for.
