摘要: 本文研究了锥形血管入口区域内血管壁与血液间的耦合运动问题.对具有锥度角的弹性血管入口区域内的管壁运动和血液流动建立了相互耦合作用的数学模型.在满足相应的边界条件下求得了一组血液流动的速度分布公式、压力分布公式以及管壁运动公式.得出了一些重要的结论.

Abstract: A problem of couple motion between vessel wall and blood in the entrance region of a tapered vessel is considered in this paper.A mathematical model of co-couple action is formed for both motion of vessel wall and blood flow in the entrance regance region of elastic vessel with tapered angle.Under the situation that the relative boundary conditions are satisfied,a set of velocity distribution formula,pressure distribution formula for the blood flow in a tapered elastic vessel are derived.Some important conclusions are obtained.
- vessel wall /
- blood flow /
- couple motion /
- tapered angle
