锥形血管中非定常流动的管壁切应力分布

The Distribution for Shear Stress of Vessel Wall in a Tapered Vessel under Unsteady Blood Flow

对锥形血管中的非定常血液流动进行了讨论，导出了管壁切应力分布的公式，在相应的数值算例中，着重讨论了锥度角及轴向距离对管壁切应力的影响．

The unsteady of blood flow in tapered vessel is discussed in this paper. The formula for distribution of shear stress of vessel wall is derived. By means of the numerical computing, the effects of tapered angle and the axial distance on the shear stress of vessel wall are analyzed.
