Water97FluidProperties

Fluid properties for water and steam (H2O) using IAPWS-IF97

The water implementation in Fluid Properties is the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam. This formulation calculates properties of water and steam using pressure and temperature as inputs. The IAPWS-IF97 formulation is split into five different regions in the phase diagram.

All five regions are implemented in the Fluid Properties module. To avoid iteration in region 3 of the IAPWS-IF97 formulation, the backwards equations from IAPWS (2014) are implemented.

Viscosity is calculated using the IAPWS 2008 formulation (IAPWS, 2008). Note that the critical enhancement has not been implemented.

Thermal conductivity is calculated using the IAPS 1985 formulation (IAPS, 1985). Although there is a newer formulation available (IAPWS, 2011), it is significantly more complicated, so has not been implemented yet.

Dissolution of a dilute gas into water is calculated using Henry's law (IAPWS, 2004).
