Information

Information

1. Purpose of model

This function is used to convert a molar flow rate of fuel components into a molar flowrate of the elements the components consist of, adding the air that is needed for combustion at given

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

No physical effects considered.

3. Limits of validity

(no remarks)

4. Interfaces

(no remarks), just input and output vectors

5. Nomenclature

(no elements)

6. Governing Equations

No governing equations, this function mainly calls the function "MolarFlowRateElements" and adds the amount of air, calculated as may be seen in record "OxygenDemand".

7. Remarks for Usage

If there are components in your fuelgas which don't have a corresponding entry in the stoichiometric coefficients record, they will just be ignored, giving a faulty elements flowrate.

8. Validation

(no remarks)

9. References
