The Compressor model represents the expansion of a fluid in a volumetric machine. It is a lumped model based on performance curves. It is characterized by two flow connector for the fluid inlet and outlet and by a mechanical connector for the connection with the generator.

The assumptions for this model are:

  • No dynamics ( it is considered negligible when compared to the one characterizing the heat exchanger).
  • No thermal energy losses to the environment
  • Isentropic efficiency based on empirical performance curve
  • Filling factor based on empirical performance curve

Modelling options

In this model, the user has the choice of providing constant isentropic and volumetric efficiencies, or providing performance curves for these two variables.
