Axiomatization Decision Log
1
Identity-Giving Function
Function class
MixingFunction
⊑ DesignedFunction
Realized in
MixingProcess
⊑ MomentumTransfer
All definitions consistently identify mixing as the identity-giving capability. ISO 15926 states 'capability of MIXING', CFIHOS mentions 'fluid mixing processes', DEXPI references 'capability of mixing', and POSC Caesar specifies 'mixes two ore more fluid ingredients'.
2
Genus Determination
Assembly
bfo:Object (BFO_0000030)
Causally unified material artefact composed of physically connected,
separable MaterialComponent parts. Satisfies
Assembly ⊑ MaterialArtifact ⊑ bfo:Object.
No domain-specific parent like 'FluidProcessingEquipment' exists in the parent_candidates (FunctionalObject, ProcessEquipment, Artefact are too abstract). CFIHOS describes mixers as 'rotating piece of equipment comprised of a driver such as a motor which rotates an agitator' - indicating causally unified equipment with removable subcomponents (motor, agitator, shaft). This points to Assembly rather than MaterialArtifact.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
MixingElement is the only universally necessary part. Other components like motors, shafts, or casings vary by mixer subtype (dynamic vs. static). The mixing element is what actually performs the fluid blending function.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— multiple distinct fluid ingredients
Outputs (O)
PortionOfFluid
— homogeneous mixture of input components
Transformation (T)
compositional blending - multiple distinct fluid streams combined into homogeneous mixture
All definitions emphasize mixing 'two or more' fluid ingredients into a blended product. The transformation is compositional rather than phase change or chemical reaction.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
Separator
Pump
Compressor
C2: Pump, Compressor. C4: Separator. Signature incompatibility: Separator takes mixed inputs and produces separated outputs (opposite transformation), Pump moves single fluid stream without compositional change, Compressor increases pressure of single stream without mixing
Cross-Standard Observations
Strong consistency across standards on the mixing function. CFIHOS provides most detail on dynamic mixer construction (motor + agitator), while ISO 15926 subtypes show comprehensive coverage of both static and dynamic variants. POSC Caesar emphasizes the container aspect which may be subtype-specific.
