摘要

这项工作的目的是提供牛顿流体在由不同直径的刚性容器组成的分支网络中的稳态流动的力学描述。这一问题的解决对于更好地理解微循环内血液流动的机制具有重要意义。所建立的分支网络模型预测了相同口径的容器中流体动压和流量的广泛分布(流动非均质性)。所得结果与简单串并联网络模型的预测结果进行了比较。结果表明,该模型能较好地逼近分支网络模型给出的平均压力和流量值。

A Model of Pressure and Flow Distribution in Branching Networks.

The objective of this work is to provide a mechanical description of steady-state flow of Newtonian fluid in a branching network that consists of rigid vessels of different diameters. Solution of this problem is of importance for better understanding of the mechanics of blood flow within the microcirculation. The developed branching network model predicts a wide distribution of the hydrodynamic pressure and flow in the vessels of the same caliber (flow heterogeneity). The obtained results are compared with predictions of a simple series-parallel network model. It is shown that this model provides an accurate approximation to the values of the mean pressure and flow given by the branching network model.
