The transient hot wire method was used to measure the thermal conductivity of the following polyatomic gases: hydrogen, nitrogen, carbon monoxide and methane. The measurements occurred in the range from 0.8-10 MPa, at 35 degrees Celsius, and have an estimated uncertainty of ±0.2%....
This article investigated the accuracy of measuring the thermal conductivity of sand with various moisture contents. Water morphologies, distribution and evolution at the pore scale were determined. Results found that sand with a moisture content lower than 25% was difficult to measure with the system. Water evaporation and diffusion prevented an accurate measurement from being collected. However, at high moisture contents the system gave excellent results....
