TwoPort

Partial model of two port

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Partial model with two flowPorts.

Possible heat exchange with the ambient is defined by Q_flow; setting this = 0 means no energy exchange.

Setting parameter m (mass of medium within pipe) to zero leads to neglect of temperature transient cv*m*der(T).

Mixing rule is applied.

Parameter 0 < tapT < 1 defines temperature of heatPort between medium's inlet and outlet temperature.
