.Annex60.Fluid.Interfaces.PartialFourPort

Information

This model defines an interface for components with four ports. The parameters allowFlowReversal1 and allowFlowReversal2 may be used by models that extend this model to treat flow reversal.

This model is identical to Modelica.Fluid.Interfaces.PartialTwoPort, except for the fowllowing:

1. it has four ports, and
2. the parameters port_a_exposesState, port_b_exposesState and showDesignFlowDirection are not implemented.

Revisions

• November 12, 2015, by Michael Wetter:
  Renamed model from FourPort to PartialFourPort. Removed parameters h_outflow_a1_start, h_outflow_b1_start, h_outflow_a2_start and h_outflow_b2_start. This is for issue #299.
• October 30, 2015, by Matthis Thorade:
  Added partial keyword to model declaration.
• October 6, 2014, by Michael Wetter:
  Changed medium declaration in ports to be final.
• October 3, 2014, by Michael Wetter:
  Changed assignment of nominal value to avoid in OpenModelica the warning alias set with different nominal values.
• November 12, 2013, by Michael Wetter:
  Removed import Modelica.Constants statement.
• September 26, 2013 by Michael Wetter:
  Added missing each keyword in declaration of nominal value for Xi_outflow.
• September 17, 2010 by Michael Wetter:
  Fixed bug: The start value for port_b1.h_outflow was set to h_outflow_b2_start instead of h_outflow_b1_start.
• February 26, 2010 by Michael Wetter:
  Added start values for outflowing enthalpy because they are often iteration variables in nonlinear equation systems.
