modelPartialIsentropicEfficiency
Based model used by all models describing isentropic efficiencies
Extends from BaseClasses.PartialEfficiency (Base model that is used to define all further efficiencies).
Information
This is a base model for overall isentropic efficiency models that
are required for various compressor models. It defines some basic
inputs and outputs that are commonly used by efficiency models and
these inputs and outputs are summarised below:
| Type | Name | Comment |
|---|---|---|
| input |
epsRef
|
Ratio of the real and the ideal displacement volume |
| input |
VDis
|
Displacement volume |
| input |
piPre
|
Pressure ratio |
| input |
rotSpe
|
Rotational speed |
| input |
staInl
|
Thermodynamic state at compressor's inlet conditions |
| input |
staOut
|
Thermodynamic state at compressor's out conditions |
| input |
TAmb
|
Ambient temperature |
| output |
ηise
|
Overall isentropic efficiency |
