modelPartialTwoNPortsInterface
Partial model with two vectors of ports and declaration of quantities for bore field models
Extends from Buildings.Fluid.Geothermal.ZonedBorefields.Interfaces.PartialTwoNPorts.
Information
This component defines the interface for models with multiple pairs of inlet and outlet ports, here implemented as two vectors of ports. It is similar to Modelica.Fluid.Interfaces.PartialTwoPortTransport, but it does not include the species balance
port_b[i].Xi_outflow = inStream(port_a[i].Xi_outflow);
Thus, it can be used as a base class for a heat and mass transfer component
The partial model extends
Buildings.Fluid.Geothermal.ZonedBorefields.Interfaces.PartialTwoNPorts
and adds quantities that are used by many models such as
m_flow_nominal, m_flow and dp.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Nominal condition | |||
| Modelica.Units.SI.MassFlowRate[nPorts] | m_flow_nominal | Nominal mass flow rate | |
| Advanced | |||
| Modelica.Units.SI.MassFlowRate[nPorts] | m_flow_small | 1E-4*abs(m_flow_nominal) | Small mass flow rate for regularization of zero flow |
| Advanced › Diagnostics | |||
| Boolean | show_T | false | = true, if actual temperature at port is computed |
Components
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Units.SI.MassFlowRate[nPorts] | m_flow | port_a[:].m_flow | Mass flow rate from port_a to port_b (m_flow > 0 is design flow direction) |
| Modelica.Units.SI.PressureDifference[nPorts] | dp | port_a[:].p - port_b[:].p | Pressure difference between port_a and port_b |
| Medium.ThermodynamicState[nPorts] | sta_a | if allowFlowReversal then Medium.setState_phX(port_a.p, noEvent(actualStream(port_a.h_outflow)), noEvent(actualStream(port_a.Xi_outflow))) else Medium.setState_phX(port_a.p, noEvent(inStream(port_a.h_outflow)), noEvent(inStream(port_a.Xi_outflow))) | Medium properties in port_a |
| Medium.ThermodynamicState[nPorts] | sta_b | if allowFlowReversal then Medium.setState_phX(port_b.p, noEvent(actualStream(port_b.h_outflow)), noEvent(actualStream(port_b.Xi_outflow))) else Medium.setState_phX(port_b.p, noEvent(port_b.h_outflow), noEvent(port_b.Xi_outflow)) | Medium properties in port_b |
