Information
In a sixth step, a junction is introduced to recombine the flow from the turbine with the bypass valve.
To obtain a balanced system (number of equations = number of unknowns), one of the junction inlets
(either A or B) must remain free, comparable to a
Sink_free boundary.
Further documentation is available in the AirCycle package.
