Air is treated as a pseudo-pure fluid using an approach adopted from previous research on the equation of state for air. The equations are valid over all liquid and vapor states, and a simplified cross-over equation was used to model the behavior of the critical enhancement for thermal conductivity. The extrapolation behavior of the equations for nitrogen and argon well below their triple points was monitored so that both could be used as reference equations for extended corresponding states applications. The uncertainties of calculated values from the equations are generally within 2{\%} for nitrogen and argon and within 5{\%} for oxygen and air, except in the critical region where the uncertainties are higher. Comparisons with the available experimental data are given.}, + doi = {10.1023/B:IJOT.0000022327.04529.f3}, + issn = {1572-9567}, + owner = {fetzer}, + timestamp = {2017.05.11}, + url = {http://dx.doi.org/10.1023/B:IJOT.0000022327.04529.f3} +} diff --git a/dumux/material/components/air.hh b/dumux/material/components/air.hh index cefc58e375..27f140353f 100644 --- a/dumux/material/components/air.hh +++ b/dumux/material/components/air.hh @@ -165,7 +165,7 @@ public: * * The pressure correction is even simpler and developed and tested by * Holger Class in 2016 against the results of the Lemmon and Jacobsen (2004) - * approach \cite LemmonJacobsen2004 + * approach \cite Lemmon2004a * It shows very reasonable results throughout realistic pressure and * temperature ranges up to several hundred Kelvin and up to 500 bar * @@ -207,7 +207,7 @@ public: /*! * \brief The dynamic viscosity \f$\mathrm{[Pa*s]}\f$ of Air at a given pressure and temperature. * - * This is a very exact approach by Lemmon and Jacobsen (2004) \cite LemmonJacobsen2004 + * This is a very exact approach by Lemmon and Jacobsen (2004) \cite Lemmon2004a * All the values and parameters used below are explained in their paper * Since they use ''eta'' for dyn. viscosity, we do it as well for easier * comparison with the paper -- GitLab
