Abstract:

The three dimensional multiscale model is introduced to study clot formation in the vessel with stenosis. The novel approach, based on separation of fluid flow calculation and red blood cells deformation, is proposed. The macro scale fluid dynamic is described by lattice Boltzmann method (LBM). The deformation of red blood cells is calculated by spectrin link method (SLM). The interaction between those two methods is handled by immersed boundary method (IBM). Simulation results demonstrate the structure of the thrombus for three simple geometries.
