Flow Splitter

fullflow.FlowSplitter

One-inlet, two-outlet flow splitter with optional energy and species conservation.

FlowSplitter divides a single incoming stream into two outlet streams while enforcing steady-state mass conservation. Optional energy conservation may be solved, and optional species conservation can be used to determine the composition of the second outlet stream.

When species conservation is enabled, the composition of outlet 1 is treated as known and the composition of outlet 2 is calculated from species mass balances.
