ABSTRACT
The tapered blood vessel is associated with the human physiological pulsatile blood flow in this study to address the questions about the developing flow. The geometry model of tapered blood vessel, theoretical models of blood flow, physiological boundary conditions and calculation conditions are proposed. An average blood flow function is established according to the physiological pulsatile flow conditions. The pulsatile flow in a 3-D tapered blood vessel is simulated numerically with the flow function. The distributions of velocity and pressure on different time of the cardiac cycle are obtained. The numerical simulation outcomes are compared with the experimental and analytical results. The characteristics of the pulsatile flow in a tapered blood vessel are discussed in this paper.
