1 Identity-Giving FunctionFunção Identitária
Function class
SeparationFunction ⊑ DesignedFunction
Realized in
SeparationProcess ⊑ PlannedProcess
The identity-giving function is separation - specifically separating solid or liquid particles from gas of different density. This reuses the existing SeparationFunction from the enriched separator class.
2 Genus DeterminationDeterminação do Gênero
separatorbfo:Object (BFO_0000030)
The most specific appropriate superclass is 'separator' which is already enriched in our ontology. Gas cyclone separator is clearly a subtype of separator, inheriting the basic separation function but with the specific cyclonic mechanism differentia.
3 Differentia SpecificaDiferença Específica
∃hasPart.CyclonicFlowChamber ⊓ ∃participatesIn.CentrifugalSeparationProcess

Distinguished by having a cyclonic flow chamber that generates centrifugal force from incoming flow for separation.

The cyclonic flow chamber and centrifugal separation mechanism are the minimal conditions that distinguish this separator type from other separators. The static device generates centrifugal force through flow geometry rather than mechanical rotation.

No necessary parts recorded.

All gas cyclone separators must have these basic components to create and utilize cyclonic flow for separation
