“…First, the melting curves (P-T curve) agree at temperatures of about 6 K and below, but differ systematically from a 0 difference at 6 K to about a 0.15 K difference at 16.5 K. (Glassford and Smith's [25] P-T curve is above the Crilly and Mills' [28] curve.) Second, the densities of Glassford and Smith [25] along the melting line disagree in a more random fashion with those of Grilly and Mills [28] by as much as 2 percent. Yigure 18 shows a pronounced systematic deviation pattern between the data of Glassford and Smith [25] and the equation of state.…”

“…This region of overlap occurs at the lowest densities measured by Glassford and Smith [25] When a comparison of Glassford and Smith's {25] data along the melting curve is made with similar data by Grilly and Mills [28], two major disagreements result. First, the melting curves (P-T curve) agree at temperatures of about 6 K and below, but differ systematically from a 0 difference at 6 K to about a 0.15 K difference at 16.5 K. (Glassford and Smith's [25] P-T curve is above the Crilly and Mills' [28] curve.)

“…Glassford and Smith [25J measured P-V-Tdata from 4.2 to 20 K at pressures from 100 to 1300 atmospheres and in the small region of overlap with Lounasmaa's data the disagreement is 1.3 percent in density. Figures 16,17,and 18 show the deviations between densities calculated using equation (17) and Lounasmaa (50 J , Edeskuty and Sherman [17], and Glassford and Smith [25], respectively.…”

Tabular values of density, internal energy, enthalpy, entropy, heat capacity, and speed of sound for liquid and gaseous helium are presented for temperatures from 2 to 1500 kelvin at pressures from 1.0 X 10 4 to 1.0 X 1O1! pascals. Diagrams of temperature vs entropy are also given. The properties presented are calculated from an equation of state which was fitted to experimental P-V-T and other thermodynamic data from the world's literature. The equation of state was fitted to these data in three separate regions of pressure and temperature. The regional equations are forced to join smoothly at the preconceived boundaries. Extensive comparisons between the equation of state and experimental data have been made, and deviation plots are presented. A particularly careful determination of the second virial coefficient over the full temperature range 2-1500 kelvin is presented. The louIe-Thomson inversion curve has been calculated and comparisons made with other sources. Equations for the density of the saturated liquid and vapor are included as well as an equation which represents the 1958 helium vapor pressure temperature scale.

“…We point out that this limit appears to be exceeded by some published high-density data. Values of c v /R up to 1.525 for 3 He and 1.585 for 4 He have been reported by Dugdale and Franck [15], and up to 1.59 by Glassford and Smith [17]. In both cases their c v data were derived from differentiation of pVT data.…”

Debye Fluid State Equation

et al. 2007

A new form of a fluid state equation, based on a conceptual extrapolation from the Debye equation for the specific heat of solid materials is described. The Debye characteristic temperature, , which is nominally a constant for solids, becomes a function of the fluid density ρ. Further assuming = c 1 ρ 2/3 (1 + c 2 ρ + c 3 ρ 2 + · · ·) yields the conventional fluid virial equation in the high-T and low-ρ limits for a monatomic fluid. Additional terms must be added to describe (a) the compressibility of the dense subcooled fluid and (b) properties in the near-critical range. Discussion of the Gruneisen parameter and other factors is included. This Debye fluid theory was used as a state equation for 3 He, continuous from 0.005 K to above room temperature.
