modelPartialHeatTransfer
Common interface for heat transfer models
Information
This component is a common interface for heat transfer models. The heat flow rates Q_flows[n] through the boundaries of n flow segments
are obtained as function of the thermodynamic states of the flow segments for a given fluid Medium,
the surfaceAreas[n] and the boundary temperatures heatPorts[n].T.
The heat loss coefficient k can be used to model a thermal isolation between heatPorts.T and T_ambient.
An extending model implementing this interface needs to define one equation: the relation between the predefined fluid temperatures Ts[n],
the boundary temperatures heatPorts[n].T, and the heat flow rates Q_flows[n].
