HydrogenFluidProperties

Fluid properties for Hydrogen (H2)

Fluid properties for hydrogen are mainly calculated using the Leachman et al. equation of state (Leachman et al., 2009). This formulation uses density and temperature as the primary variables with which to calculate properties such as density, enthalpy and internal energy.

When used with the pressure and temperature interface, which is the case in the Porous Flow module, hydrogen properties are typically calculated by first calculating density iteratively for a given pressure and temperature. This density is then used to calculate the other properties, such as internal energy, directly.

Viscosity is calculated using the formulation presented in Muzny et al. (2013). Thermal conductivity is calculated using the relationship presented in Assael et al. (2011)

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