Thermal Conductivity in Radial Fuel Rod Gap

The equations are
$$k_{mix}=\sum^3_{a=1}\frac{x_ak_a}{\sum^3_{b=1}x_b\phi_{ab}}$$
$$\phi_{ab}=\frac{1}{\sqrt{8}}(1+\frac{MW_a}{MW_b})^{-0.5}[1+(\frac{MW_a}{MW_b})^{0.5}(\frac{MW_a}{MW_b})^{0.25}]^2$$
Where 1 is Helium, 2 is Krypton, and 3 is Xenon. In these equations \(x\) is the mole fraction. \(MW\) is the molecular weight. \(k\) is the thermal conductivity of each gas species.
