thermalConductivityEstimateThermal conductivity of polyatomic gases(Eucken and Modified Eucken correlation) |
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This function provides two similar methods for estimating the
thermal conductivity of polyatomic gases.
The Eucken method (input method == 1) gives good results for low temperatures,
but it tends to give an underestimated value of the thermal conductivity
(lambda) at higher temperatures.
The Modified Eucken method (input method == 2) gives good results for
high-temperatures, but it tends to give an overestimated value of the
thermal conductivity (lambda) at low temperatures.
