Package 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

Version Info and Revision history

• First implemented: July, 2000 by Hubertus Tummescheit

• Initial version: July 2000
• Documented and re-organized: January 2003
