Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
SeparationFunction ⊑ DesignedFunction
Realized in
SeparationProcess ⊑ PlannedProcess
All definitions emphasize separation as the identity-giving function - separating fluids, solids dispersed in fluids, or two fluids of different density. This aligns with the already-enriched SeparationFunction used by centrifuge, separator, scrubber, and filter.
2 Genus DeterminationDeterminação do Gênero
Separatorbfo:Object (BFO_0000030)
Separator is already enriched in the ontology with SeparationFunction and Vessel genus. Hydrocyclone is a specific type of separator that uses centrifugal/hydraulic forces. The parent candidates CYCLONE and CYLINDRICAL VESSEL are too broad - cyclone encompasses atmospheric phenomena, and cylindrical vessel is purely geometric. Separator captures the functional essence while being the most specific appropriate superclass.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.ConicalSection ⊓ ∃participatesIn.CentrifugalSeparationProcess

Uses centrifugal/hydraulic forces generated by tangential fluid flow through a conical geometry to achieve separation.

The conical geometry and centrifugal separation process are the key differentiating features that distinguish hydrocyclones from other separation equipment. The tangential feed creates a vortex in the cone that enables density-based separation.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These four components are universally required for hydrocyclone operation: the cone creates the separation chamber, tangential inlet generates vortex, and dual outlets allow separation of phases by density.

TransformationTransformação
density-based separation using centrifugal force
Hydrocyclones take a mixed fluid stream and separate it into two streams based on density differences using centrifugal force generated by tangential flow through conical geometry.
Disjoint WithDisjunto com
Centrifuge
C1: Centrifuge. Centrifuges use rotating mechanical parts while hydrocyclones are stationary devices - these represent incompatible separation mechanisms
