中高温下原子氢和惰性气体二元混合输运性质的物理力学计算

PHYSICO-MECHANICAL CALCULATIONS OF TRANSPORT PROPERTIES OF BINARY MIXTURES OF ATOMIC HYDROGEN AND NOBLE GASES AT INTERMEDIATE AND HIGH TEMPERATURES

本文应用Tang—Toennies势模型确定了原子间的势,在此基础上,计算了H—He,H—Ne,H—A_r二元混合稀薄气体在中、高温(100k以上)下,氢的摩尔百分数为0.25惰性气体的为0.75时的输运性质。在T=273,333k两个温度点,所计算的H—He系统的扩散系数与最近的测量值进行了比较,二者符合得很好。

In this paper, the potential between the atoms are determinated using Tang-Toennies potential model, by which, the transport properties of dilute binary gassous mixtures H-He, H-Ne and H-Ar, in which the mol percentage is 25 for hydrogen, and 75 for noble gases, are calculated at intermediate and high temperatures ( above 100K ) . At 273 and 333K, the diffusion coefficients calculated in this manner is compared with tke recently measured values[l3,14], and a better result is achieved.
