Thermal Conductivity of Propane

Thermal conductivity measurements for nitrogen in the dense gaseous state

“…Instead, the coaxial cylindrical cell was selected for construction because it offers better flexibility of operation and its design allows best the introduction of improvements. The results already obtained by others (14, 16,24,27,28,29,39,48,52) indicate that a coaxial cylindrical cell is most dependabIe and produces thermal conductivities that are reliable.…”

“…had to be provided with fine thermocouple wires, it became necessary to construct the outer cylindm from two cylindrical shells. In order to assure good thermal contact between these shells so that they would behave as a homogeneous solid, pressure-fitting techniques have been used in the past (24,27,28,29). However, for the construction of this cell, advantage was taken only of the thermal expansion characteristics of the material (stainless steel 304) of these two shells.…”

Intermolecular potential energy surface and thermophysical properties of propane

“…6, the thermal conductivity values obtained using the adjusted potential function, λ adj , are compared with those obtained using the unadjusted one, λ unadj , with a large number of experimental data sets, [63][64][65][66][67][68][69][70][71][72][73][74][75] with the zero-density part of the correlation of Marsh et al, 74 and with the recommended reference values of Younglove and Ely. 76 We extrapolated the data of Zheng et al 72 at 323.75 K and the steady-state hot-wire data of Marsh et al 74 to zero pressure.…”

Thermal conductivity: Reduced state correlation for ethylene and its application to gaseous aliphatic hydrocarbons and their derivatives at moderate pressures

“…These results indicate that this figure may apply to other multicomponent systems containing ethylene. In the absence of reliable experimental data Figure 5 Thermal conductivity data at atmospheric pressure for organic compounds (4, 6,9,10,11,12,14,15,17,23,25,26) in the gaseous state were segregated into homologous series to determine if Figure 5 applies to each family of substances. Quasicritical thermal conductivities for each substance were calculated by dividing k", values from Figure 5 into available experimental k" values.…”
