General

This component is an expansion of Component 18 (Splitter with ratio specification) to three outlets. Here Pin 2 is regarded as the main outlet and Pins 3 and 4 as branchings.

For each of the two branchings, you can choose whether the branching mass flow is to be specified from outside or calculated via a specification value relative to the inlet mass flow.

Pressure and enthalpy are equated with the input values at all outlets.

Like Component 18, also Component 140 can be used for shafts and electric lines in order to model a distribution of mechanical energy and electrical output respectively.

To keep the component clearly arranged, not all possibilities to combine specifications that would result from a combination of two Components 18 have been implemented. If a case is required that cannot be covered with Component 140, two Components 18 will have to be applied.

User Input Values

FMODE	Flag for local calculation mode Expression = 0: GLOBAL = 1: Off-design mode = -1: Local Design mode
FM3	Specification first branch Like in Parent Profile (Sub profile option only) Expression = 0: Flow 3 calculated from specification value M3M1 = 1: Flow 3 given from outside
M3M1	First branch flow relative M1
FM4	Specification second branch Like in Parent Profile (Sub profile option only) Expression = 0: Flow 4 calculated from specification value M4M1 = 1: Flow 4 given from outside
M4M1	Second branch flow relative M1

Generally, all inputs that are visible are required. But, often default values are provided.
