Parameters

Name	Description
nspecies	Number of components

Modelica.Media.Common.ThermoFluidSpecial.ThermoBaseVars

Information

Model description

ThermoBaseVars is inherited by all medium property models and by all models defining the dynamic states for the conservation of mass and energy. Thus it is a good choice as a restricting class for any medium model or dynamic state model.

Parameters

n	Discretization number
nspecies	Number of species

Modelica.Media.Common.ThermoFluidSpecial.ThermoProperties

Information

Model description

A base class for medium property models which work with most of the versions of dynamic states that are available in the ThermoFluid library. Currently used by all ideal gas models.

nspecies	Number of species

Modelica.Media.Common.ThermoFluidSpecial.ThermoProperties_ph

Information

Model description

A base class for medium property models which use pressure and enthalpy as dynamic states. This is the preferred model for fluids that can also be in the two phase and liquid regions.

Modelica.Media.Common.ThermoFluidSpecial.ThermoProperties_pT

Information

Model description

A base class for medium property models which use pressure and temperature as dynamic states. This is a reasonable model for fluids that can also be in the gas and liquid regions, but never in the two-phase region.

Modelica.Media.Common.ThermoFluidSpecial.ThermoProperties_dT

Information

Model description

A base class for medium property models which use density and temperature as dynamic states. This is a reasonable model for fluids that can be in the gas, liquid and two-phase region. The model is numerically not well suited for liquids except if the pressure is always above approx. 80% of the critical pressure.
