modelDynamicSplitterN
Splitter with 1 inlet and N outlets, taking dynamic pressure into account
Extends from ThermofluidStream.Utilities.DropOfCommonsPlus.
Information
Dynamic variant of the generic splitter with one upstream connection and N downstream connections. This model accounts for dynamic pressure/momentum effects and is suitable for transient analyses where inertial behavior in branching nodes is relevant. Be aware that dynamic formulations can increase model stiffness and nonlinear complexity.
In general the component has two non-linear equation systems of size 1. This can be resolved by setting Advanced->assumeConstantDensity=true (default: false).
considerInertance
For the parameter considerInertance, refer to Idealized.UsersGuide.InertanceNeglect.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | assumeConstantDensity | true | = true, if incompressibility is assumed (use '= false' for Ma > 0.3) |
| Integer | N | 1 | Number of outlets |
| SI.Area | A_in | Inlet cross section area | |
| SI.Area[N] | A_out | Cross section area of outlets | |
| Advanced | |||
| SI.Area | A_splitter | 0.1 | Internal cross section area |
| Boolean | considerInertance | dropOfCommons.considerInertance | =true, if transient momentum (inertance) term is considered; disable only for advanced use |
| Utilities.Units.Inertance | L | dropOfCommons.L | Inertance of each inlet/outlet |
