“…The methodology for calculating the thermal conductivity of gas mixtures is identical in both codes (with the exception of one difference in the fourth and fifth significant digits of the "a" parameter for steam (H 2 O)) and agrees with that described in Hagrman et al Gambhir et al (1967), and Brokaw (1969). The Kr model is based on data from Kannuluik and Carman (1952), von Ubisch (1959), Zaitseva (1959), and Gambhir et al (1967). The Xe model is based on data from Kannuluik and Carman (1952), Zaitseva (1959), and Gambhir et al (1967).…”

“…Differences of only 5AE0.4% are found for the very old experimental datum by Weber [48] at 273 K and also for a value by Kannuluik and Carman [49] at the same temperature. But for the complete temperature range of the measurements of Kannuluik and Carman between 90 and 580 K the deviations increase up to À3%.…”

A neon-neon interatomic potential energy curve determined from quantum-mechanical ab initio calculations and described with an analytical representation (R. Hellmann, E. Bich, and E. Vogel, Molec. Phys. 106, 133 (2008)) was used in the framework of the quantum-statistical mechanics and of the corresponding kinetic theory to calculate the most important thermophysical properties of neon governed by two-body and three-body interactions. The second and third pressure virial coefficients as well as the viscosity and thermal conductivity coefficients, the last two in the so-called limit of zero density, were calculated for natural Ne from 25 to 10,000 K. Comparison of the calculated viscosity and thermal conductivity with the most accurate experimental data at ambient temperature shows that these values are accurate enough to be applied as standard values for the complete temperature range of the calculations characterized by an uncertainty of about AE0.1% except at the lowest temperatures.

“…Figure 5 shows the theoretical variation of thermal conductivity with temperature using VSS and LJ models and a linear interpolation of experimental measurements [12,13] [18,19,20,21,22,23]. Again, the LJ model more accurately predicts the thermal conductivity -being within the ±2% measurement error beyond 500 K.…”

Abstract. The effect of molecular models on viscosity and thermal conductivity calculations is investigated. The Direct Simulation Monte Carlo (DSMC) method for rarefied gas flows is used to simulate Couette and Fourier flows as a means of obtaining the transport coefficients. Experimental measurements for argon (Ar) provide a baseline for comparison over a wide temperature range of 100-1,500 K. The variable hard sphere (VHS), variable soft sphere (VSS), and Lennard-Jones (L-J) molecular models have been implemented into a parallel version of Bird's one-dimensional DSMC code, DSMC1, and the model parameters have been recalibrated to the current experimental data set. While the VHS and VSS models only consider the short-range, repulsive forces, the L-J model also includes constributions from the long-range, dispersion forces. Theoretical results for viscosity and thermal conductivity indicate the L-J model is more accurate than the VSS model; with maximum errors of 1.4% and 3.0% in the range 300-1,500 K for L-J and VSS models, respectively. The range of validity of the VSS model is extended to 1,650 K through appropriate choices for the model parameters.
