Abstract: Abstract In this paper, the blood hydrokinetic characteristics in the bifurcation deformity blood vessel have been studied with the viscosity fluid boundary element methods. Besides the movement laws of the bloodstream in the branch tube, the changes of the blood flow have been studied when there is flow- round particle in the blood vessel. The problems of the bloodstream have also been studied when deformity takes place and there is particulate matter in the blood vessel. And some situations are indicted, such as the velocity vector distribution of the blood flow, the shear stress distribution on the blood vessel wall, and the pressure distribution on the surface of the flow-round particle. The results show that the particle unsteadies at the main axis. It can move towards the high speed direction when it deviates due to some disturbances. The conclusion is consistent with the test result of the literature [1]. The method of the paper turns the problem of handling about viscous flow from the area into the one of the boundary so as to lower one dimension in calculation. It is very flexible and convenient to divide solving inner point value from the boundary. It needs less EMS memory, but with great accuracy. It provides a worthy approach for numerical calculation of bio-fluid engineering and other correlation domains.
