The Effect of Diffusion and Shear on Concentration Correlations in Binary Systems
The preparation of glass free from optical inhomogeneities is an example in which mixing by combined interdiffusion and shearing occurs . In principle, if the initial conditions and transport coefficients are known, the diffusion equation with a suitable connective term can be solved to follow the course of mixing provided the flow is laminar. Generally, however, the system is partially randomized to start with, so that a statistical description is necessary to define the degree of homogeneity . It is the purpose of this paper to follow the development of this description as it is changed by diffusion and a particular flow distribution.
