Thermal conductivity of air.Glenn J Tattersall
The thermal conductivity, k, of a substance is defined as the quantity of heat, Q, transmitted due to a unit temperature gradient, in a direction normal to a surface of unit area in unit time under steady–state conditions and where heat transfer is dependent only on the temperature gradient...
We have used the transient hot-wire technique to make absolute measurements of the thermal conductivity of dry, CO 2 -free air in the temperature range from 312 to 373 K and at pressures of up to 24 MPa. The precision of the data is typically ±0.1%, and the overall absolute uncertainty...
figures, it can be concluded that changes in thermal conductivity due to atmospheric variations can be neglected in most cases. Also, it was noted that the thermal conductivity at atmospheric pressure is almost proportional to the absolute temperature. Let us check the correctness of this rule-of...
In several earlier issues ofElectronics Cooling, I discussed the thermal conductivity of air as a function of temperature and pressure. Therein, it was stated that the temperature dependence cannot be neglected, but that the pressure dependence, under ‘normal’ conditions, is virtually absent...

The thermal conductivity of a representative endothermic hydrocarbon aviation kerosene fuel RP-3 was accurately measured using the classical transient hot-wire method at sub- and supercritical pressures. The measured data cover a temperature range of 285 K to 513 K and a pressure range of 0.1 MPa...
High-temperature PCMs with high thermal conductivity can accelerate the rate at which energy acts on the entire material, improving the thermal energy usage efficiency while lowering energy loss. The thermal conductivity is measured by λ (W·m−1·K−1); the more extensive the λ of the ...
