Abstract

The use of a Couette viscometer with coaxial cylinders enables us to measure the viscosity of red blood cell suspensions, the shear rate varying from 0.017 5 s-1 to 128 s-1. Red blood cells aggregation and deformation states are obtained by fitting a rheological relation on experimental results. Different types of suspensions are studied. An application to pathological cases is proposed.

Abstract

Etude de la cinétique d'agrégation érythrocytaire dans un écoulement de Couette. Une théorie de la lumière transmise et rétrodiffusée par une suspension sanguine a été étudiée en tenant compte de l'agrégation et de l'orientation des particules dans un écoulement de Couette. Les résultats théoriques permettent d'interpréter quantitativement les mesures expérimentales de la lumière laser rétrodiffusée par une suspension sanguine dans un écoulement de Couette. On propose une relation entre la taille des rouleaux et le taux de cisaillement moyen.
