Drum (separator / recirculation drum)
Config type: "Drum"
Source: crates/components/src/drum.rs
EN
Purpose & model
Liquid/vapor separator used in flooded recirculation architectures. Splits a two-phase feed into liquid and vapor outlets; may accept an evaporator return.
Thermodynamics: equilibrium separation at drum pressure (quality split toward x≈0 liquid / x≈1 vapor legs), mass and energy balances across ports.
Residuals & n_equations()
Multi-port balance residuals (mass + energy + pressure consistency). Exact count depends on active ports and edge wiring; treat as a multi-equation node — see unit tests and n_equations() in source.
Ports (4-port naming)
| Port | Role |
|---|---|
feed_inlet |
two-phase feed |
evaporator_return |
return from flooded evaporator |
liquid_outlet |
liquid to pump / recirculation |
vapor_outlet |
vapor to compressor suction |
Calibration
No primary Z-factor set; geometry/level control may be added in specialized builds.

System note
A flooded plate topology is often Drum + recirculation + DX exchanger — not a mode of BPHX alone. Shell-and-tube flooded use FloodedEvaporator.
