single-wall carbon nanotubethermal conductivityspecific heat capacitythermal potential energyIn this paper, the thermal conductivity of Single-wall carbon nanotubes (SWCNTs) is determined by lattice vibrations (phonons) and free elections. The thermal conductivity of SWCNTs is modeled up to 8-300 K ...
The results of pool boiling experiments with synthetic (CVD) diamond and silicon carbide (SiC) heaters are presented for water as boiling liquid. The diamond and SiC heaters varied considerably in thermal conductivity, but they had smooth, nearly identical surfaces, also in regard to their contact...
where k is the thermal conductivity of the wall material, A is the area of the surface normal to the heat flow direction, dx is the thickness of an elementary layer (of total thickness l), and θ is the temperature at the surface determined by the abscissa x. The temperature to the le...
Thermal conductivity of helium: A probe for the repulsive wall of the interatomic potential The thermal conductivity, k, of a 99.9999% pure helium sample is measured using the column method in the temperature range 400–2500 K. The various data se... BJ Jody,SC Saxena,VPS Nain,... - 《...
