functiongetRealGasGCV_xM

Adaptive function for gross calorific value calculation for real gases from molar GCVs, input x and M

Extends from TransiEnt.Basics.Icons.Function.

Information

1. Purpose of model

This model is used to calculate the gross calorific value (GCV), also known as higher heating value (HHV) of a fuel gas mixture based on mole fractions and molar mass and respective molar calorific values from a record.

7. Remarks for Usage

If there are components in the gas which don't have a corresponding entry in the GCVm 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.
