This component transports fluid between its two ports, without storing mass or energy. Energy may be exchanged with the environment though, e.g., in the form of work. PartialTwoPortTransport is intended as base class for devices like orifices, valves and simple fluid machines.

Three equations need to be added by an extending class using this component:

Moreover appropriate values shall be assigned to the following parameters:


This is similar to Modelica.Fluid.Interfaces.PartialTwoPortTransport except that 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.
