| Abstract: | This thesis examines the mixing of microspheres with blood flow in the lumen to understand the efficacy of the liver radioembolization procedure. The lattice Boltzmann solver Musubi is employed in order to facilitate blood flow simulations in a stenosed channel, modelling the hepatic artery. Results indicate that at the lower physiological Reynolds range, flow remains laminar with minimal particle dispersion, while at higher Reynolds range, flow departs from the laminar regime introducing onset of turbulence. The turbulence subsequently enhances the mixing of particles with the blood; the intensity of mixing is proportional to the turbulent intensity. Particle injection during the deceleration phase of the cardiac cycle seems to be favourable for maximal dispersion. |
