packageFluidPh
This package contains components that use a generic fluid with p,h as states, possibly undergoing phase transition.
Extends from Modelica.Icons.Package (Icon for standard packages).
Information
This package contains models of physical processes and components using water or steam as working fluid.All models use the StandardWater medium model by default, which is in turn set to Modelica.Media.FluidPh.StandardWater at the library level. It is of course possible to redeclare the medium model to any model extending Modelica.Media.Interfaces.PartialMedium (or PartialTwoPhaseMedium for 2-phase models). This can be done by directly setting Medium in the parameter dialog, or through a local package definition, as shown e.g. in Test.TestMixerSlowFast. The latter solution allows to easily replace the medium model for an entire set of components.
All models with dynamic equations provide initialisation support. Set the initOpt parameter to the appropriate value:
- Choices.Init.Options.noInit: no initialisation
- Choices.Init.Options.steadyState: full steady-state initialisation
- Choices.Init.Options.steadyStateNoP: steady-state initialisation (except pressure)
- Choices.Init.Options.steadyStateNoT: steady-state initialisation (except temperature)
