POLYTROPIC_EFFICIENCY

Description​

POLYTROPIC_EFFICIENCY is required to be specified under the MODELS keyword when the model is of TYPE COMPRESSOR_CHART and the CHART_TYPE is either GENERIC_FROM_INPUTor GENERIC_FROM_DESIGN_POINT. The polytropic efficiency will be a fixed number for all rate/head values in the compressor chart.

Format​

MODELS:
  - NAME: <name of model>
    TYPE: COMPRESSOR_CHART
    CHART_TYPE: <GENERIC_FROM_INPUT or GENERIC_FROM_DESIGN_POINT>
    POLYTROPIC_EFFICIENCY: <polytropic efficiency of the compressor (fixed number)>
    UNITS:
      EFFICIENCY: <polytropic efficiency unit, FRACTION and PERCENTAGE.>
    ...
