摘要:

提出了一个多组分带电硬球体系的Enskog-Landau动力学方程。它是由Liouville方程在修正的边界条件下,用非平衡统计算符方法得到的。在此基础上,用Chapman-Enskog方法在一级近似下求得了二元混合物的正规解和输运系数,如体粘滞系数、体粘滞数值计算的所有输运系数的混合物Ar-Kr,Ar-Kr,Kr-Kr与不同浓度的化合物已经评估的情况下的存在和不存在的长程库仑相互作用。并与其它理论和实验结果进行了比较。

英文摘要:

An Enskog-Landau kinetic equation for a many-component system of charged hard spheres is proposed. It has been obtained from the Liouville equation with modified boundary conditions by the method of nonequilibrium statistical operator. On the basis of this equation the normal solutions and transport coefficients such as bulk kappa and shear eta viscosities, thermal conductivity lambda, mutual diffusion D^{αβ} and thermal diffusion D_T^αhave been obtained for a binary mixture in the first approximation using the Chapman-Enskog method. Numerical calculations of all transport coefficients for mixtures Ar-Kr, Ar-Xe, Kr-Xe with different concentrations of compounds have been evaluated for the cases of absence and presence of long-range Coulomb interactions. The results are compared with those obtained from other theories and experiment.
