Required Cards:

EOS <string>

EOS WATER

Specifies the fluid for which EOS applies.

Optional Cards:

DENSITY <string> <optional parameters>

DENSITY CONSTANT <float>

Units of density should be in kg/m^3.

DENSITY EXPONENTIAL <float> <float> <float> (ref. density [rho0], ref. pressure [p0], compressibility)

Exponential function: rho0 * exp(compressibility*(pressure - p0))

DENSITY DEFAULT

Default water EOS based on International Formulation Committee of the Sixth International Conference on Properties of Steam (1967)

ENTHALPY <string> <optional parameters>

ENTHALPY CONSTANT <float>

Units of enthalpy should be in J/kmol.

VISCOSITY <string> <optional parameters>

VISCOSITY CONSTANT <float>

Units of viscosity should be in Pa-s (dynamic viscosity).

TEST <float> <float> <float> <float> <int> <int> <string> <string> <optional string>

Tests the equation of state (currently water density only). The order of the arguments are temperature low [C], temperature high [C], pressure low [Pa], pressure high [Pa], number of temperatures, number of pressures, temperature distribution [uniform,log], pressure distribution [uniform,log], optional filename
