modelGCVSensor

Sensor calculating the gross calorific value of real gas mixtures at 25 C

Extends from TransiEnt.Components.Sensors.RealGas.Base.RealGas_SensorBase (Base class for gas sensors).

Information

1. Purpose of model

Gross calorific value sensor and enthalpy flow rate sensor for VLEFluidTypes.

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

(no remarks)

3. Limits of validity

Can only be used for VLEFluidTypes.

4. Interfaces

GasPortIn, GasPortOut and RealOutpus for GCV.

5. Nomenclature

GCV in [J/kg]

EnthalpyFlowRateOut in [W]

6. Governing Equations

GCV = sum(xi_i*GCV_i)

EnthalpyFlowRateOut=gasPortIn.m_flow*NCV

7. Remarks for Usage

Gross calorific values of the pure components are defined in the record TransiEnt.Basics.Records.GasProperties.GrossCalorificValues.

8. Validation

Tested in check model "TransiEnt.Components.Sensors.RealGas.Check.TestRealGasSensors"
