modelEngineEfficiency

Fitted engine efficiency

Extends from Utilities.EngineEfficiency.PartialEngineEfficiency (Based model used by all models describing engine efficiencies).

Parameters

TypeNameDefaultDescription
BooleanuseIseWor (from PartialEngineEfficiency)false= true, if isentropic work is used to compute compressor's power consumption
