Abstract

Ventricular Assist Devices (VADs) are pumps which support failing hearts. While considered by some surgeons as gold standard treatment, current VADs have many complications related to the imposed stress on the blood. In particular, damage to the leukocytes may contribute to infections, currently the biggest post-surgical problem. Our aim was to create a numerical model of a leukocyte
which can be used to investigate leukocyte deformation in VADs. The leukocyte was modelled as a compound liquid droplet and solved in OpenFOAM using the multiphaseInterfoam solver. Initial results are presented for different shear rates, extensional versus planar shear, and for different nucleus sizes.
