Heart attack and stroke are the leading causes of death in the world. Often the main reason for this phenomenon is the clogging of arteries. This project aims is analyzing the flow in the artery-clogging effects. In the present study unsteady flow and flow also developed before is completely eroded. After parsing several different models, the Careau model for the simulation of non-Newtonian fluid in the blood is considered. The following research vessels of different sizes Eclipse model is analyzed. In the case where the output is narrowing the vessels have been strongly accelerating and up to 12% faster dilemma can be seen. However, the software cannot simulate tear, but the power of the threshold of bearing pressure on the wall tissue suggests that up to 50 percent of the eclipse diameter is tolerable. Pressure values in the vessels by flooded 80 percent of the inner diameter with Eclipse reflects the diversity of pressure and speed with high intensity within the veins that causes in areas near Eclipse values of shear stress to considerably increase the flow, vessel wall under pressure.
