.ThermofluidStream.Media.XRGMedia.R1234yf_ph.getPhase_ps

Number of phases by pressure and entropy

Information

This function computes the number of phases for R1234yf depending on the inputs for absolute pressure and specific entropy. It makes use of cubic spline functions for liquid and vapor specific entropy.

Interface

function getPhase_ps
  extends Modelica.Icons.Function;
  input Modelica.Units.SI.Pressure p "pressure";
  input Modelica.Units.SI.SpecificEntropy s "specific entropy";
  output Integer phase "number of phases";
end getPhase_ps;
