Information

1. Purpose of model

This model is used to calculate the mass specific net calorific value (NCV), also known as lower heating value (LHV) of a fuel gas mixture based on 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

NCV is the net 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 NCV values record, they will just be ignored, giving a faulty calorific value. The function will throw a warning.

NCVIn was added to give the possibility to define a constant calorific value. If this value is set to 0, the NCV will be calculated by the composition of the medium.

8. Validation

(no validation or testing necessary)
