Modelica.Media.Water.IF97_Utilities.BaseIF97.TwoPhase

Steam properties in the two-phase region and on the phase boundaries

Information

Package description

Package TwoPhase provides functions to compute the steam properties in the two-phase region and on the phase boundaries

Package contents

Function WaterLiq_p computes properties on the boiling boundary as a function of p
Function WaterVap_p computes properties on the dew line boundary as a function of p
Function WaterSat_ph computes properties on both phase boundaries and in the two phase region as a function of p
Function WaterR4_ph computes dynamic simulation properties in region 4 with (p,h) as inputs
Function WaterR4_dT computes dynamic simulation properties in region 4 with (d,T) as inputs
