Comparison between benoist and selengut diffusion coefficients in one-velocity theory when absorbing media are present in the cell

Abstract

Using heterogeneous formalism we calculated Selengut equivalent diffusion coefficient and absorption cross-section for a heterogeneous cell, containing absorbing media. The observed deviation between Benoist and Selengut diffusion coefficients and also between average and Selengut absorption cross-sections are almost exactly compensated by cell-edge flux normalisation in the thermal group.
