论文摘要
低密度下,以较大的温度和摩尔分数计算了氦,霓虹灯,氩和k的二元,三元和季节混合物的粘度和导热性,并采用了Chapman-Enskog方法。为了计算欧米茄的综合性,采用了原子间电位。粘度和热导率的相对数值误差分别不超过1.e-6和1.e-5。与原子间电位相关的相对不确定性约为0.1%。本文献可用的其他论文中报道的当前数据的比较表明,此处考虑的运输系数的准确性显着提高。
The viscosity and thermal conductivity of binary, ternary and quaternary mixtures of helium, neon, argon, and krypton at low density are computed for wide ranges of temperature and molar fractions, applying the Chapman-Enskog method. Ab initio interatomic potentials are employed in order to calculate the omega-integrals. The relative numerical errors of the viscosity and thermal conductivity do not exceed 1.e-6 and 1.e-5, respectively. The relative uncertainty related to the interatomic potential is about 0.1%. A comparison of the present data with results reported in other papers available in the literature shows a significant improvement of accuracy of the transport coefficients considered here.
