.TransiEnt.Basics.Functions.GasProperties.molarFlowRateElements

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.

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, a for-loop is used to iterate through the vector of component names. The stoichiometric coefficients concerning the elementary composition of each component, served in a special record, are then multiplied by the molar flowrate of the component.

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

For validation see the partial models.
