CO2FluidProperties

Fluid properties for carbon dioxide (CO2) using the Span & Wagner EOS

Fluid properties for CO $var element = document.getElementById("moose-equation-27ce550d-3bb9-4a74-af3b-4d5f5ca97a6c");katex.render("_2", element, {displayMode:false,throwOnError:false});$ are mainly calculated using the Span and Wagner equation of state (Span and Wagner, 1996). This formulation uses density and temperature as the primary variables with which to calculate properties such as density, enthalpy and internal energy. However, the Fluid Properties module uses pressure and temperature in its interface, which is suitable for use in the Porous Flow module. As a result, CO $var element = document.getElementById("moose-equation-de263580-7d38-471a-bca2-c4b64aa122be");katex.render("_2", element, {displayMode:false,throwOnError:false});$ 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 Fenghour et al. (1998), while thermal conductivity is taken from Scalabrin et al. (2006).

Dissolution of CO $var element = document.getElementById("moose-equation-677c011f-ec1d-4a72-b5da-69ddfa72e35f");katex.render("_2", element, {displayMode:false,throwOnError:false});$ into water is calculated using Henry's law (IAPWS, 2004).
