A correlation of thermal conductivity data for helium

Measurements of Hydrogen Thermal Conductivity at High Pressure and High Temperature

“…Figure 8b shows the density dependence of the thermal conductivity of helium as measured in the region of temperatures shown in Fig. 8a Fluid fit to the plotted data while the dotted line shows the trend of the correlation by Hands and Arp [32]. Based on this figure, the density dependence has only a small effect at low pressures.…”

“…All of the data (both experimental and theoretical) in Fig. 8a are within ±0.6 % of the dilute-gas component of the correlation by Hands and Arp [32]. Based on the data shown in Fig.…”

“…Figure 8 shows a comparison of published measurements in the vicinity of room temperature and reference correlations available from the literature. The correlation by Hands and Arp [32] is formulated into the NIST reference database [33]. Unlike the correlations by Bich et al [34] and Kestin [35], the ab initio quantum mechanical calculations by Hurly and Moldover [31] have the feature that they did not involve the use of any measurements of the transport property data.…”

A determination of the molar gas constantRby acoustic thermometry in helium

“…The thermal boundary layer correction also depends on pressure (or density) in a two-fold way: i) by the pressure dependence of the density and the isobaric heat capacity of the gas in the thermal penetration length; ii) by the density correction d/d of the thermal conductivity, with different literature sources [6,44,45] …”

Experimental and numerical results on transient heat transfer to supercritical helium at low temperatures

“…According to Hands and Arp [13] the error in the thermal conductivity of supercritical helium is about 5% This gives rise to the same inaccuracy in the calculated values of the heat flux ~b, tube temperature T and heat transfer coefficient h.…”
