摘要:
扩散系数是传质过程的一个重要参数 .描述多组分物系传质过程的基本方程是 Maxwell-Stefan(MS)方程,其定义的扩散系数表征物系中组分间的分子间相互作用力 .传统上应用的 Fick扩散系数,包括了分子间相互作用力和热力学非理想性两种因素的影响,要准确计算比较困难 .文中讨论多组分物系扩散传质过程 MS扩散系数、Fick扩散系数的意义,以及两者的关系和计算方法
Abstract:
Diffusivity is an important parameter of the mass transfer process. Maxwell Stefen (MS) equation is the basic equation for describing mass transfer process of multicomponent mixture. MS diffusivity characterizes the interaction force of molecules among the components in the mixture. Fick diffusivity in conventional use includes the influences of intermolecalar interaction force and thermodynamic imperfection which is fairly difficult to calculate accurately. The author discusses the significance of MS dcffusivity and Fick diffusivity of multicomponent mixture during mass transfer process, their relation and their calculation.
