Fully-Developed Interface

A fully-developed interface is used to specify the periodic pressure drop for periodic (cyclic) repeats. Although it makes most physical sense that this type only be applied to periodic interfaces, it is not restricted to periodic interfaces.

Applications

Fully developed flow in a tube or channel

Modeling

For both the Coupled and Segregated Flow models, the pressure jump

is specified at the interface.

For the Segregated Flow model, the mass flow rate

may be specified instead of the pressure jump.

Compatibilities

May only be used between regions belonging to the same fluid continuum

Fully-developed periodic heat transfer cannot be accommodated. Therefore, if energy is activated in the simulation, the boundaries of the fully-developed continuum must be adiabatic.

If the mass flow rate is specified, there can be no inlets or outlets connected to the continuum containing the interface. In addition, specifying the mass flow rate typically does not make sense for an in-place interface.

User Interface

This interface type adds a fully developed flow option interface condition to the tree when the Segregated Flow model is used. The property setting of this condition adds either of the following interface values:

Pressure jump

Mass flow rate
