Example - adiabatic process
Extends from Modelica.Icons.Example (Icon for runnable examples), ThermofluidStream.Idealized.Tests.Processes.Adiabatic.PartialFixed (Base class).
Information
This example illustrates several variants of using the Adiabatic process defined by parameters (outlet state and mass flow rate given, FullMedium model)
