Correction to: Ab Initio Calculated Results Require New Formulations for Properties in the Limit of Zero Density: The Viscosity of Methane ($$\hbox {CH}_4$$)

摘要: A wide-ranging formulation for the viscosity of methane in limit zero density is presented. Using ab initio calculated data Hellmann et al. (J Chem Phys 129, 064302, 2008) from 80 K to 1500 K, functional form was developed by guided symbolic regression with constraints correct extrapolation \(T \rightarrow 0\) and high-temperature limit. The adjusted recalibrated experimental May (Int J Thermophys 28, 1085–1110, 2007) so that these are represented within their estimated expanded uncertainty 0.053 % (\(k = 2\)) temperature range 210.756 391.551 K. Based on comparisons original ratio measurements, new correlation outside this be 0.2 700 0.5 1100 1 physically at higher temperatures. At temperatures below 210 agrees 0.3 down 150 extrapolates without a singularity \(T\rightarrow 0\).
