Viscosity and Thermal Conductivity of Binary Gas Mixtures: Krypton-Argon, Krypton-Neon, and Krypton-Helium

Abstract

The coefficients of viscosity and thermal conductivity of binary mixtures of krypton with argon, neon and helium have been determined over the full range of composition of each mixture at a pressure of 70 cm of mercury and at a temperature in the range 18.0 to 18.3°C. The experimental values are compared with theoretical values based on the Lennard-Jones (6-12) potential of interaction between molecules. Agreement between the experimental and calculated values is generally satisfactory, but there are discrepancies between some of the measurements given here and those of other workers.
