【 摘 要 】

Advances in modern medical imaging technology and three-dimensional modeling technology provide basic support for the establishment of individual cardiovascular models, which can promote the close integration of cardiovascular hemodynamics research. In this paper, the fluid-solid coupling technology is used to obtain the numerical simulation results of blood on rigid and elastic vessel walls. The results show that the elastic deformation of the wall has an important influence on the hemodynamic characteristics. The peak velocity in elastic blood vessel is about 3.7 % higher than that in rigid blood vessel. The extremum of fluid pressure in elastic blood vessel is about 9.1 % higher than that in rigid blood vessel.
