phaseBoundaryAssert

Assert function for checking threshold to phase boundary

Information

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

This function is used as a guard for property functions using pTX as an input. Property functions for two-phase media using pressure and temperature as inputs shall not be used close to the phase boundary in order to avoid errors and high deviations for just small deviations in the input arguments. The refrigerant state can not be determined in the two-phase region using pressure and temperature.

Syntax

phaseBoundaryAssert(p, T)

Inputs (2)

p

Type: Pressure (Pa)

Description: Refrigerant pressure

T

Type: Temperature (K)

Description: Refrigerant temperature
