# Drum (separator / recirculation drum)
|
||
|
||
Config type: `"Drum"`

|
||
### 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.
|
||
|
||
### JSON (main)
|
||
|
||
| Key | Meaning | Default |
|
||
|-----|---------|---------|
|
||
| `fluid` / refrigerant | working fluid | primary |
|
||
| level / volume options | if exposed | – |
|
||
|
||
### System note
|
||
|
||
A **flooded plate** topology is often Drum + recirculation + DX exchanger — not a mode of BPHX alone. Shell-and-tube flooded use `FloodedEvaporator`.
