Scale scaling segregation

When indeed the state of segregation is a small-scale segregation, then each particle at a certain point will, on the average, be surrounded by-other particles which have an average concentration which is characteristic for the point in consideration. When c is the concentration in a particular particle and c is the average concentration in all of the particles at the point of interest, then...

Danckwerts expresses the goodness of mixing by two statistically defined quantities, the scale and the intensity of segregation. He states that his treatment is suitable chiefly for mixtures where the smallest particles capable of independent movement are very small compared to the size of the portions which will normally be taken for use or analysis. For his analysis, he assumes that the mixture is uniform in texture that is, it cannot be divided into two parts of equal size in which the mean concentration or the scale or intensity of segregation differ significantly. He further states This is the most important limitation on the practical value of the definitions and tests which will be proposed. He emphasizes the fact that large scale segregation, caused for example by... 

Transmission electron microscopy of samples with <30 wt % PCL showed no evidence of segregation of components. However, samples with higher PCL contents did show evidence of fine-scale segregation. The results of image analysis were consistent with a ceramer with 46 wt % PCL having co-continuous microphases [176]. 

In contrast with the previous two sections, where the models focused on the segregation dynamics at the particle-scale level, in this section, we focus on a model developed for the evolution of macro-scale segregation pattern. 

If the chain ends are segregated on the surface at the start of the welding, then the same general scaling law applies but with different values of r and s for some of the number properties. The average properties remain unaffected [1]. 

Continuous releases of concentrated HjS streams must be segregated in a separate flare system to limit the extent of fouling and plugging problems. Releases of HjS such as diversion of sour gas product to flares during shutdown or upset of a downstream sulfur recovery unit are considered to be continuous, but safety valve releases are not included in this category. However, if a special HjS flare system is provided for continuous releases, the concentrated HjS safety valve releases should be tied into it rather than into the regular flare system. Due to the nature of HjS one should plan on frequent inspection and flushing of HjS flares to remove scale and corrosion products.

An important parameter characterizing the laminar regime is the intersegment spacing over which the species must diffuse to be able to react. For kinetic control, as opposed to diffusion control of the reaction, this spacing must not exceed a certain scale of segregation given by [53J ... 

Like sulphur, phosphorus appears to have little effect on the overall scaling of iron alloys in air. It may, however, play a role in suppressing breakaway oxidation in carbon steels in CO/CO2 environments. Donati and Garaud " found that the tendency for breakaway was lower over ferrite, where P segregates. To confirm this, the authors doped pure Fe with P and found that...
