Information

1. Purpose of model

This model represents a compressed gas storage for real gases.

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

The model consists of a volume, in which the gas located. Pressure losses inside the volume and during charging and discharging are neglected. There is no discretisation of the flow field or the heat transfer. The heat transfer is modelled using a replacable heat transfer model, the default model uses a constant heat transfer coefficient.

3. Limits of validity

The model is only valid for negligible pressure losses and negligible changes of the heat transfer coefficient (other heat transfer models can be used). For high pressures there are errors due to errors in the gas models.

4. Interfaces

gasPortIn and gasPortOut: Real gas input and output

heat: heat port for the heat flow into/out of the storage

p_storage: signal output of the gas pressure

5. Nomenclature

(no elements)

6. Governing Equations

Simple mass and energy balances are used.

7. Remarks for Usage

(no remarks)

8. Validation

No validation necessary because only fundamental equations are used.
