.TransiEnt.Components.Gas.Compressor.Base.PartialCompressorRealGas_L1_simple

Information

1. Purpose of model

This model is a partial model for real gas compressors. It is a modified version of the model ClaRa.Components.TurboMachines.Compressors.CompressorGas_L1_simple from ClaRa version 1.2.1. The model is documented there and here only the changes are described.

2. Level of detail, physical effects considered, and physical insight

The model was changed to work with real gases and mechanical and electrical efficiencies were added.

3. Limits of validity

Only valid for real gases and positive pressure differences. Variable efficiencies and time-dependent behavior are not considered.

4. Interfaces

gasPortIn: real gas inlet

gasPortOut: real gas outlet

m_flow_in: input for mass flow rate in kg/s

V_flow_in: input for volume flow rate in m3/s

P_el_in: input for electrical power in W

P_shaft_in: input for shaft power in W

dp_in: input for pressure difference in Pa

mpp: mechanical power port (if useMechPowerPort)

5. Nomenclature

Delta_p "pressure increase"

P_hyd "Hydraulic power"

P_shaft "Drive power"

P_el "Electrical power"

V_flow "Volume flow rate"

6. Governing Equations

(no remarks)

7. Remarks for Usage

useMechPowerPort and use_P_elInput cannot be true at the same time since the electric power is then calculated outside of the compressor.

8. Validation

(no remarks)

9. References
