Information

1. Purpose of model

Net 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 RealOutput for NCV and EnthalpyFlowRateOut.

5. Nomenclature

NCV in [J/kg]

EnthalpyFlowRateOut in [W]

6. Governing Equations

NCV = sum(xi_i*NCV_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.NetCalorificValues.

8. Validation

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

10. Version History

Model created by Lisa Andresen (andresen@tuhh.de) in Jun 2016

Model modified by Oliver Schülting (oliver.schuelting@tuhh.de) in Jul 2019: added enthalpy flow rate

Model modified by Robert Flesch (flesch@xrg-simulation.de), Nov 2020: added NCV in different flow directions

Model modified by Carsten Bode (c.bode@tuhh.de), Feb 2021: set evaluate=true for flowDefinition to avoid nonlinear system of equations
