Fundamental Study for Simulation of Blood Cell Motion in a Blood Vessel

ABSTRACT

PURPOSE: The objective of this study is to investigate the blood cell motion in human capillary by applying the boundary singularity method. METHODS: A particle motion of spherical shape falling in a vertical tube filled with Newtonian fluid is studied by using the boundary singularity method and the experiment. RESULTS AND CONCLUSION: As the eccentric ratio increases up to 0.6, the rotational velocity increases almost linearly and the falling velocity remains constant. However, as the eccentric ratio exceeds 0.6, the rotational velocity increases rapidly and the falling velocity decreases. As the tube radius increases, falling velocity increases and approaches the stokes velocity and the rotational velocity decreases.
