Performance evaluation of simulated smoothed particle hydrodynamics method in pulsating atherosclerotic blood vessel

Abstract

Blood flow in pulsating atherosclerotic blood vessel is simulated numerically using the smoothed particle hydrodynamics method. In this paper, we are concerned with its implementation in Matlab. We run the simulation with 7600 fluid particles and 1602 boundary particles. We improve the boundary model of arterial wall deformation together with the inlet and outlet boundary conditions to form a two-dimensional model of a stenosed pulsating artery. We also create a non-penetrating condition at the arterial wall while maintaining a stable flow in the interior. We present the performance evaluation of the simulation and some finding of enhancement in numerical calculation.
