Abstract: The three-dimensional Lattice Boltzmann model has been applied to the study of rigid particle suspensions through a quasi-two-dimensional modelled arterial stenosis. Only when two particles are positioned symmetrically to the centerline to an extremely high accuracy, the particles can be blocked completely at the stenosis throat. Particles incline to gather near the centerline for a stenosis throat width b < 2d, consistent with the observation that red blood cells tend to concentrate near the center of the vessel. The present study shows that the quasi-two-dimensional system is an effective model to study the behaviour of three-dimensional multi-particle suspension in stenotic arteries.
