Partial component with two ports

Information

This partial model defines an interface for components with two ports. The treatment of the design flow direction and of flow reversal are predefined based on the parameter allowFlowReversal. The component may transport fluid and may have internal storage for a given fluid Medium.

Implementation

This model is similar to Modelica.Fluid.Interfaces.PartialTwoPort but it does not use the outer system declaration. This declaration is omitted as in building energy simulation, many models use multiple media, an in practice, users have not used this global definition to assign parameters.

Parameters

TypeNameDefaultDescription
Assumptions
BooleanallowFlowReversaltrue= false to simplify equations, assuming, but not enforcing, no flow reversal

Connectors

TypeNameDefaultDescription
Modelica.Fluid.Interfaces.FluidPort_aport_aFluid connector a (positive design flow direction is from port_a to port_b)
Modelica.Fluid.Interfaces.FluidPort_bport_bFluid connector b (positive design flow direction is from port_a to port_b)

Revisions

  • June 18, 2024, by Michael Wetter:
    Added start and nominal attributes to avoid warnings in OpenModelica due to conflicting values.
    This is for IBPSA, #1890.
  • January 18, 2019, by Jianjun Hu:
    Limited the media choice. See #1050.
  • July 8, 2018, by Filip Jorissen:
    Added nominal value of h_outflow in FluidPorts. See #977.
  • November 19, 2015, by Michael Wetter:
    Removed parameters port_a_exposesState and port_b_exposesState for #351 and showDesignFlowDirection for #349.
  • November 13, 2015, by Michael Wetter:
    Assinged start attribute for leaving enthalpy at port_a and port_b. This was done to make the model similar to Buildings.Fluid.Interfaces.PartialFourPort.
  • November 12, 2015, by Michael Wetter:
    Removed import statement.
  • October 21, 2014, by Michael Wetter:
    Revised implementation. Declared medium in ports to be final.
  • October 20, 2014, by Filip Jorisson:
    First implementation.
