modelPartialEfficiency

Base model that is used to define all further efficiencies

Information

This is a base model for efficiency models that are required for various compressor models. It defines some basic inputs that are commonly used by efficiency models presented in AixLib.Fluid.Movers.Compressors.Utilities.EngineEfficiency, AixLib.Fluid.Movers.Compressors.Utilities.IsentropicEfficiency and AixLib.Fluid.Movers.Compressors.Utilities.VolumetricEfficiency. These inputs are summarised below:
