[The boundary element study on arterial bifurcation vessel flow].
In this paper a kind of arterial bifurcation vessel's hemodynamic characteristics are studied with the boundary element method, and the blood flowing velocity vector distributions are calculated when there is pathologic change in the branch vessel wall and when there is no pathologic change. The shear stress value at the lateral wall and that at the medial wall are compared when there is pathologic change in the main branch vessel wall and when there is no pathologic change. Moreover, the flow field distribution and the pressure on the particle surface are calculated, when there is flow-round particle at the place of bifurcation. The move tendency of the particle is judged, and the possible factors in causing atherosclerosis are analyzed.
