modelConstantEfficiency
General model that describes a constant overall volumetric efficiency
Extends from PartialVolumetricEfficiency (Based model used by all models describing volumetric efficiencies).
Information
This model contains a simple calculation procedure for volumetric efficiency models (for more information, please check out AixLib.Fluid.Movers.Compressors.BaseClasses.PartialCompression). The model provides a constant overall volumetric efficiency and is the most basic engine efficiency model.
