Axiomatization Decision Log
1
Identity-Giving Function
Function class
CompressionFunction
⊑ DesignedFunction
Realized in
CompressionProcess
⊑ MomentumTransfer
The identity-giving function is compression - all definitions specify 'compress and supply' or 'blowing' which involves pressurizing gas. This is the same CompressionFunction that defines compressors in general, as blowers are a specific type of compressor for medium pressure applications.
2
Genus Determination
Compressor
Blower is a specific type of compressor distinguished by operating at medium pressure and medium volume flow. The enriched 'compressor' class already exists with CompressionFunction. Among parent candidates, 'compressor' is the most specific appropriate superclass that captures the compression identity.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These are the universal components needed for any blower to realize its compression function, regardless of specific design (axial, centrifugal, etc.)
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfGas
— at ambient or low pressure
Outputs (O)
PortionOfGas
— at medium pressure, medium volume flow rate
Transformation (T)
mechanical energy added to gas to increase pressure and maintain medium volume flow
Blowers take low-pressure gas and deliver it at medium pressure with medium volume flow, distinguishing them from fans (low pressure rise) and high-pressure compressors
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.
Disjointness Axioms
Fan
C?: Fan [kind_ambiguous]. Fans operate at low pressure rise with high volume flow (incompatible signature), while vacuum pumps create negative pressure rather than positive compression
Cross-Standard Observations
All three sources (ISO 15926, CFIHOS, POSC) consistently define blowers as medium pressure, medium volume flow compression devices. ISO 15926 uses the term 'blowing' while CFIHOS/POSC explicitly mention 'compress and supply', but both refer to the same compression function.
