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 study aimed to determine the thermal conductivity of gas-filled Metal Organic Framework (MOF) materials. Glass beads were used as the reference material, and nitrogen (N2) and helium (He) were added to the MOF materials. A TPS instrument measured the thermal conductivity of the MOF samples using the Transient Plane Source (TPS) method. Results showed that the MOF materials containing copper had higher thermal conductivities than iron-filled materials, and the ...
The purpose of this study was to fabricate and analyze the physical properties of polyacrylate–gold nanocomposites (PGNs) with gold nanoparticles (GNPs) as their nucleation agents. The transient plane source (TPS) method was used to measure the thermal properties of the polyacrylate–gold nanocomposite foams (FPGNs) and PGNs. Results showed that the addition of GNPs improved thermal conductivity of the PGN materials, but as the size of GNPs increased, the ...
