modelGCVSensor
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"
