.Modelica.Media.R134a.R134a_ph.bubbleEntropy

Information

This function calculates the liquid phase entropy of R134a from the state variable p (absolute pressure). It is modelled by cubic splines which are fitted with non-equidistant grid points derived from the fundamental equation of state of Tillner-Roth and Baehr (1994) and the Maxwell criteria.

Restrictions

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