Extends from Modelica.Icons.Example (Icon for runnable examples), ThermofluidStream.Idealized.Utilities.IconInertanceNeglect (Icon for considerInertance = false).
Information
In a fourth step, the ram air mass flow rate is determined based on the specified temperature difference at heatExchangerSideB.
Since the compressor outlet pressure is varying with time this inverse calculation requires considerInertance = false, also see
UsersGuide.InertanceNeglect.
Further documentation is available in the AirCycle package.
