.TransiEnt.Storage.Gas.GasStorageVesselHeatTransfer_L2

Information

1. Purpose of model

This model represents an gas storage vessel for real gases.

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

This model uses the models GasStorage_constXi_L2 or GasStorage_varXi_L2 and can be used for real gases with constant or variable compositions. A heat transfer to the ambient is considered using a wall model (ClaRa.Basics.ControlVolumes.SolidVolumes.CylindricalThickWall_L4 from ClaRa, it can be neglected if wished so) and an outer heat transfer model.

3. Limits of validity

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

4. Interfaces

gasPortIn: Real gas output

gasPortOut: Real gas input

p_gas: signal output of the gas pressure
