.AixLib.Fluid.Movers.Compressors.Utilities.EngineEfficiency.PowerEngineEfficiency .AixLib.Fluid.Movers.Compressors.Utilities.EngineEfficiency.PowerEngineEfficiencyThis model contains a calculation procedure for engine efficiency models (for more information, please check out AixLib.Fluid.Movers.Compressors.BaseClasses.PartialCompression). The calculation procedures based on a power approach are presented below.
Actually, one power approache is implemented in this package. To
add further calculation procedures, just add its name in AixLib.Fluid.Movers.Compressors.Utilities.Types
and expand the if-structure.
