Note
-
Estimation methods for gases are not included, as they are rather complicated to apply, typically requiring structural information, heat capacity data, and viscosity data. If all that information is available, it is quite likely that experimental thermal conductivity data are also available — in which case, those should be used instead.
-
Estimation methods for liquids are also not included, as none of those reported in the literature are considered sufficiently reliable. Nonetheless, below the normal boiling point, most organic liquids have thermal conductivities between 0.1 and 0.2 W /(m·K), which can be used as a first approximation.
