Berdichevsky equation

In conclusion, the most correct description of the phenomena in a packed bed is a form of the coupling equation like the Berdichevsky equation. The van Deemter equation provides the most practical representation of the packed bed. 

For r e r, this relationship leads to a Fredholm integral equation of the second type for the field Ey within the region F. The Green s function for the background sequence, Gb, which is present in equation (9.21) can be calculated from a simple recursive formula. Details about this procedure can be found in a monograph by Berdichevsky and Zhdanov (1984).
