modelHACoilInside
Calculates the hA value for water inside a coil
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
Model for convective heat transfer coefficients inside a coil. Optionally, the convective heat transfer coefficient can be computed as a function of temperature and mass flow rate.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real | n | 0.85 | Water-side exponent for convective heat transfer coefficient, h proportional to m_flow^n |
| General › Nominal condition | |||
| Modelica.Units.SI.MassFlowRate | m_flow_nominal | Water mass flow rate | |
| Modelica.Units.SI.ThermalConductance | hA_nominal | Convective heat transfer coefficient | |
| Modelica.Units.SI.Temperature | T_nominal | Modelica.Units.Conversions.from_degC(20) | Nominal water temperature |
| Advanced › Modeling detail | |||
| Boolean | flowDependent | true | Set to false to make hA independent of mass flow rate |
| Boolean | temperatureDependent | true | Set to false to make hA independent of temperature |
Connectors
