Numerical simulation of clotting processes: A lattice Boltzmann application in medical physics

In this paper, the concurrent numerical simulation of clotting and unsteady flow within a stenosed artery is described. The simplified blood clotting process is based on a residence time model, using a lattice Boltzmann flow solver with passive scalar advective-diffusive transport. Simulation results of a stenosed model artery are presented together with experimental blood analogue results. Aspects of an efficient unstructured implementation are briefly reviewed.
