In the implementation of a flow models that function with Modelica Standard Library DynamicPipe (or a similar model that builds from PartialTwoPortFlow) there are examples of flow models that take place in an environment with heat transfer that requires wall properties (e.g., heatPorts.T and/or heatPorts.Q_flow) in order to calculate the pressure drop.
For example, a pressure drop model may need to calculate a new visocisty or Prandtl number based on the medium pressure and the wall temperature to capture cooling/heating effects, etc.
The heat transfer model obtains properties of the medium via passing the "states" however there is no existing connection in DynamicPipe or PartialTwoPortFlow that goes the other way.
I've tried numerous variations of ideas and have had no success, including creating a new PartialTwoPortFlow that contains all the heat transfer calls that exist in DynamicPipe.
I hesitate to post this question as I am surprised I am having so much difficulty with this and would not be surprised to find a straight forward solution. Nevertheless I need this ability and curious if others have already solved this issue as I am running short on ideas.
So my questions is:
What is a proper/efficient means of passing the heatPorts.T values to the flowModel?
