A LATTICE BOLTZMANN MODELING OF BLOODFLOW IN CEREBRAL ANEURYSMS

We present numerical simulations of bloodflow in cerebral aneurysms, obtained with the open source software Palabos which provides a flexible, highly parallelized and publicly available environment for the lattice Boltzmann (LB) method. LB models are promising tools for biomedical modeling that compares well with more traditional CFD techniques and can be easily augmented to include non-Newtonian rheology or biological processes. In this paper we shall discuss a LB model describing the formation of a thrombus in a cerebral aneurysmal cavity, whether spontaneous or induced by a flow diverter (stent).
