Predictions for Hemolysis Properties in Shear Blood Flows of the Pipe-Orifice : (2nd Report, Effects of Particle Inertia and Contact with Wall)

Abstract

This paper describes the particle inertia and the contact with the wall of red blood cells on the variance of particle path, that should depend on the hemolysis properties. The new methods of examining the inertia of red blood cells (particle) on particle path are discussed using computational fluid dynamics (CFD). In this method, the particles are moved by Stokes drag including effects of difference between density of plasma and internal liquid in the blood. The results of analysis by this method show that (1) the diameter of the particle (red blood cell) that means inertia of the cells, (2) the configuration of the objective wall boundary are important factor. These results also show that if the inertia and the contact with the wall are considered, the precision of the prediction of the hemolysis properties will be progressed.
