Abstract
Thrombosis plays a crucial role in atherosclerosis or in haemostasis when a
blood vessel is injured. This article focuses on using a meshless particle-based Lagrangian
numerical technique, the smoothed particles hydrodynamic (SPH) method, to study the
flow behaviour of blood and to explore the flow parameters that induce formation of a
thrombus in a blood vessel. Due to its simplicity and effectiveness, the SPH method is
employed here to simulate the process of thrombogenesis and to study the effect of various
blood flow parameters. In the present SPH simulation, blood is modelled by two sets of
particles that have the characteristics of plasma and of platelet, respectively. To simulate
coagulation of platelets which leads to a thrombus, the so-called adhesion and aggregation
mechanisms of the platelets during this process are modelled by an inter-particle force
model. The transport of platelets in the flowing blood, platelet adhesion and aggregation
processes are coupled with viscous blood flow for various low Reynolds number scenarios.
The numerical results are compared with the experimental observations and a good
agreement is found between the simulated and experimental results.
