Axiomatization Decision Log
1
Identity-Giving Function
Function class
MultipathFluidConveyanceFunction
⊑ DesignedFunction
Realized in
MultipathFluidConveyanceProcess
⊑ MomentumTransfer
ISO 15926 defines the tube bundle by what its assembly achieves — 'allowing multiple flow paths from a single source' — which is a conveyance function distinguishing it from a single tube.
2
Genus Determination
Assembly
bfo:Object (BFO_0000030)
Causally unified material artefact composed of physically connected,
separable MaterialComponent parts. Satisfies
Assembly ⊑ MaterialArtifact ⊑ bfo:Object.
ISO 15926 types it as a BUNDLE consisting of several tubes assembled together; a plurality of parts held as one makes iof-core:Assembly the correct root.
3
Necessary Parts
| Part class | Parent | Relation |
|---|---|---|
| Tube | MaterialArtifact | hasComponentPartAtAllTimes |
Tube is named as a sub-component in the ISO 15926-4 definition ("consists of several tubes assembled together"); one hasComponentPartAtAllTimes restriction asserted, source-grounded (corrects a prior stale rationale claiming no part could be quoted).
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— fluid stream entering from a single source
Outputs (O)
PortionOfFluid
— same fluid divided among parallel tube paths
Transformation (T)
division of a single fluid stream among multiple parallel tube paths
The bundle does not change the fluid, only the number of paths it takes.
5
Axiom Mode Decision
Necessary conditions only
— modelled as a primitive universal
(⊑, SubClassOf). Identity is grounded in designed
function and cannot be reduced to a property checklist.
The differentia is the structural fact of several tubes assembled together; not sufficient under OWA.
Reviewer Notes
ODR-022 §O6: standard-term component of 'shell and tube heat exchanger'. Admitted to the pipeline because it is a term in a source standard AND that standard states it is a component of that equipment (verbatim source_quote in the owning entry). Awaiting expert review.
