Extends from TransiEnt.Basics.Icons.Model (Icon for models), TransiEnt.Basics.Media.Base.RealGas_MediaBaseGCV.
Information
1. Purpose of model
This model is used to calculate the mass specific gross calorific value (GCV), also known as higher heating value (HHV) of a fuel gas mixture based on the mass fractions and repective mass weighted calorific values from a record.
2. Level of detail, physical effects considered, and physical insight
(no remarks)
3. Limits of validity
(no remarks)
4. Interfaces
(no remarks)
5. Nomenclature
xi_in is the mass fraction
GCV is the gross calorific value
6. Governing Equations
(no remarks)
7. Remarks for Usage
If there are components in the gas which don't have a corresponding entry in the GCV values record, they will just be ignored, giving a faulty calorific value. The function will throw a warning.
GCVIn was added to give the possibility to define a constant calorific value. If this value is set to 0, the GCV will be calculated by the composition of the defined medium.
8. Validation
(no validation or testing necessary)
