Turbine#

class Turbine(*args, **kwarg)[source]#

Bases: Converter

A turbine component model for gas turbine and turbofan engines.

tag#

Identifier for the turbine. Default is ‘Turbine’.

Type:

str

mechanical_efficiency#

Efficiency of mechanical power transmission. Default is 1.0.

Type:

float

polytropic_efficiency#

Efficiency of the expansion process accounting for losses. Default is 1.0.

Type:

float

Notes

The Turbine class models the expansion and work extraction process in a turbine stage. The model includes:

  • Work extraction calculations

  • Pressure ratio effects

  • Temperature changes

  • Efficiency losses

  • Mechanical power transmission

  • Real gas effects

Major Assumptions

  • Efficiencies do not change with varying conditions

Definitions

‘Mechanical Efficiency’

Ratio of shaft power output to gas power extraction

‘Polytropic Efficiency’

Measure of expansion process efficiency accounting for losses
