Segregation of flow

In calculations of this kind, two different equations of mixing according to Dankwerts131 are usually used one for micromixing and one for complete segregation of flows. The imperfect reactor operation can be taken into account by means of the curve of residence time distribution and various empirical combinations of elementary reactor volumes based on it.
