modelSink_T
Model of a sink with temperature for reverse flow as an input that can be exported as an FMU
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
Model of a sink that takes as an input the medium properties
temperature, mass fractions (if Medium.nXi > 0)
and trace substances (if Medium.nC > 0).
These properties are used during reverse flow.
For a system of components with the connectors of the Buildings.Fluid.FMI package, this component is required to set the medium properties for the reverse flow.
If the parameter use_p_in is set to true,
then the model has an output connector p.
This can be used to obtain the pressure of the sink, which
may be needed to iteratively solve for the mass flow rate.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | use_p_in | true | = true to use a pressure from connector, false to output Medium.p_default |
| Assumptions | |||
| Boolean | allowFlowReversal | true | = true to allow flow reversal, false restricts to design direction (inlet -> outlet) |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Blocks.Interfaces.RealInput | T_in | Prescribed boundary temperature | |
| Modelica.Blocks.Interfaces.RealInput | X_w_in | Prescribed boundary composition | |
| Modelica.Blocks.Interfaces.RealInput[Medium.nC] | C_in | Prescribed boundary composition | |
| Interfaces.Inlet | inlet | Fluid port | |
| Buildings.Fluid.FMI.Interfaces.PressureOutput | p | Pressure |
