Transport Property of Air (thermal conductivity)

This equation computes the thermal conductivity of air at a specified temperature

INPUTS

T - temperature in Kelvin degrees

NOTES

Transport properties of a substance describe the movement of particles within that substance from one point to another.  The transport properties of air have a use in the study of thermal plasmas in technological applications. Use of thermal conductivity is required when modeling energy and viscous flow.

The quantities that appear in this equation are understood to be in MKS units.  The equation has the following defined variable values:

`T_0` (reference temperature) = 300 `""^@`K

`T_A` (ambient air temperature) = 245.4 `""^@`K

`T_B` (boiling/Botlzmann temperature) = 27.6 `""^@`K

`kappa_0` (reference value in kg/m-s) = 1.846E-5 `kg/(m*s)`

REFERENCES

There is a nice writeup of the different researches undertaken to refine the calculations for High Temperature Air Transport Property Components in the "Plasma Chemistry and Plasma Processing" journal (Vol 16, No. 1, 1996 (Supplement) ). In this article, M. Capitelli, R. Celiberto, C. Gorse, D. Giordane, review and compare the results of  "critically old and new efforts made to obtain transport cross sections (collision integrals) and kinetic equations used to calculate the transport properties"

This journal article presents an evaluation of the lineage of the individual researches and opens some results to question.
