Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This function shall be used in order to calculate the thermodynamic state record for the vapor phase boundary. It requires the saturation record as input which can be determined by both functions setSat_p and setSat_T:

Example:

    Medium.AbsolutePressure p=3e5;
    // Viscosity on the vapor phase boundary
    Modelica.SIunits.DynamicViscosity eta_vap;

    equation

    eta_vap = Medium.DynamicViscosity(Medium.setBubbleState(Medium.setSat_p(p)));

Restrictions

It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
