Prediction of concentration profiles during erythrocyte sedimentation by a hindered settling model

Abstract

The effect of diffusion on the sedimentation of erythrocytes is reexamined analytically. and it is concluded that the diffusivity of erythrocytes is too small by several orders of magnitude to account for the available experimental results. An alternative monodisperse hindered sedimentation model is found to give fairly good agreement with the available experiments, at least after 1 hr. A polydisperse hindered sedimentation model is considered briefly, but it is found to be unable to completely account for the limitations of the monodisperse model.
