Extension of a description of mass diffusion in binary fluids based on Fick's law to multicomponent fluids requires introduction of diffusion matrices. A problem is that Fick diffusion matrices commonly adopted for multicomponent fluids depend on the velocity frame of reference. In this paper we show how one can define Fick diffusion matrices for multicomponent fluids that are frame invariant.
将基于菲克定律的二元流体质量扩散描述扩展到多组分流体需要引入扩散矩阵。一个问题是，多组分流体通常采用的菲克扩散矩阵取决于参考速度系。在本文中，我们展示了如何为多组分流体定义与参考系无关的菲克扩散矩阵。
