Abstract: The majority of deaths in developed countries are from cardiovascular diseases. Thrombosis is severe cause in the arterial diseases associated with under physiologic conditions myocardial infarction and stroke. It is known that most cardiovascular diseases are associated with some form of abnormal blood flow in arteries. In this thesis, the arteries are classified by arteriole-capillary intersections and side branch-postcapillary venule intersections. The 3-D models of different degree of blood vessels are modeled by Pro/ENGINEER. After defining the models conditions, it is separately carried out in ANSYS Fluent and ANSYS CFX to obtain the Newtonian fluid and Non-Newtonian fluid cases results. Based on the experiment observation, the velocity, shear strain rate and vorticity are considered as the key variables for analyzing the initiation and formation of thrombosis. In addition, it is indispensable to compare with different fluid properties for the purpose of realizing the real simulations.
