Abstract

In this study, we numerically and theoretically  investigated the effect of magnetic field on shape of red cells. The two phase model was used for the dynamics of red cells.  We considered red cells as deformable drops flowing through a flat microfluidic channel. We employed boundary element method (BEM) to numerically solve the two-dimensional Darcy equation by applying magnetic normal stress as a boundary condition at the interface of red cells and blood plasma. Our numerical and theoretical  results indicate that red cells elongate in direction of magnetic fields. The final stable shape is a result of the  balance between the surface energy and the magnetic energy of the drop. Our numerical and theoretical results are in good agreements with the experimental results.
