thermal conductivity vs pressure
thermal conductivity vs pressure
(OP)
How does the thermal conductivity of air (and water) vary with increasing pressure?
What about gases in general?
Can anyone provide guidance here?

see the excellent book by Poling el al. "The properties of gases and liquids".

RE: thermal conductivity vs pressure
Generally the answer is yes for gases, no for liquid water.
In general, the thermal conductivity of gases increases with both pressure and temperature, but more related to temperature than pressure. The effect is negligible for fairly low pressures (near atmospheric), but becomes more significant at a few hundres PSI or so.

Pure gas (nitrogen, oxygen, etc.) thermophysical properties including thermal conductivity at a wide range of pressures are given in

I should have added water to the list of pure substances the properties of which can be found in the same site.
