WOLFRAM SYSTEM MODELER
MassFlowSource_TIdeal flow source that produces a prescribed mass flow with prescribed temperature, mass fraction and trace substances |
SystemModel["Modelica.Fluid.Sources.MassFlowSource_T"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Models an ideal flow source, with prescribed values of flow rate, temperature, composition and trace substances:
If use_m_flow_in
is false (default option), the m_flow
parameter
is used as boundary pressure, and the m_flow_in
input connector is disabled; if use_m_flow_in
is true, then the m_flow
parameter is ignored, and the value provided by the input connector is used instead.
The same thing goes for the temperature and composition
Note, that boundary temperature, mass fractions and trace substances have only an effect if the mass flow is from the boundary into the port. If mass is flowing from the port into the boundary, the boundary definitions, with exception of boundary flow rate, do not have an effect.
