modelGasStorage_constXi_L1
L1: Model of a simple gas storage volume for constant composition
Extends from Base.PartialGasStorage_L1.
Information
1. Purpose of model
This model is a model for simple gas storage for real gases with constant composition.
2. Level of detail, physical effects considered, and physical insight
The specific enthalpies are passed through, there is no energy balance. The pressure is constant.
3. Limits of validity
The model is only valid if pressure and temperature of the gas are not of interest.
4. Interfaces
gasPortIn and gasPortOut: Real gas input and output
5. Nomenclature
(no elements)
6. Governing Equations
Simple total and component mass balances are used.
7. Remarks for Usage
useXiConstParameter can be used to either use the inStream value of gasPortIn or xi_const for the composition.
8. Validation
No validation necessary because only fundamental equations are used.
9. References
