WOLFRAM SYSTEM MODELER
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Interface and base class for a momentum balance, defining the mass flow rate
of a given
Medium in a flow model.
The following boundary flow and force terms are part of the momentum balance and must be specified in an extending model (to zero if not considered):
Ib_flow, the flow of momentum across model boundaries,
F_p[m], pressure force, and
F_fg[m], friction and gravity forces.
The length of the flow path
pathLength is an input that needs to be set in an extending class to complete the model.
Description: = true to allow flow reversal, false restricts to design direction (m_flow >= 0)
