thermalConductivity

Return thermal conductivity of dry air (simple polynomial, moisture influence small, valid from 123.15 K to 1273.15 K, outside of this range linear extrapolation is used)

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Thermal conductivity is computed from temperature using a simple polynomial for dry air. Range of validity is from 123.15 K to 1273.15 K. The influence of pressure is neglected.
