Blood flow in human arteries considered as an important aspect of health care. Due to the large amount of difficulties conducting in-vivo experiments, the use of computational fluid dynamics (CFD) to simulate pulsatile flow in the blood artery has become a promising alternative approach. In this paper the 2-dimensional model of blood flow in the rectangular coordinates is formed by numerical approach and the simulation by Unity Engine is provided. The simulation showed that the blood flow was laminar within the artery. The velocity magnitude of blood was highest at the center of the artery and gradually decreased towards the walls due to the no-slip condition. These results are consistent with previous experimental and computational studies of blood flow in arteries.
