Interface and base class for
m momentum balances, defining the mass flow rates
of a given
m flow segments.
The following boundary flow and force terms are part of the momentum balances and must be specified in an extending model (to zero if not considered):
Ib_flows[m], the flows of momentum across segment boundaries,
Fs_p[m], pressure forces, and
Fs_fg[m], friction and gravity forces.
The lengths along the flow path
pathLengths[m] are 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_flows >= zeros(m))
Description: Number of flow segments
Description: Formulation of momentum balance
Type: MassFlowRate (kg/s)
Description: Start value of mass flow rates
Type: Length[m] (m)
Description: Lengths along flow path
Description: System properties
