【摘要】 实际分离的混合物大多数为多组分体系,因此,开展多组分传质过程的理论和实验研究具有重要的实际意义。多组分传质过程涉及Fick扩散系数和axwell-Stefan扩散系数的计算。本文阐述Fick扩散系数和Maxwell-Stefan扩散系数的意义和相互关系,以及多组分液体体系扩散系数的计算。更多还原

【Abstract】 Most of mixtures to be separated are multicomponent systems,therefore,the theoretical and experimental research on multicomponent mass transfer has great significance.Multicomponent mass transfer deals with the calculation of Fick and Maxwell-Stefan diffusion coefficients.In the paper,the meaning and calculation on Maxwell-Stefan and Fick diffusion coefficients in liquid multicomponent system were discussed.更多还原
