In this paper, the authors extend their study of wall mechanics given in Part 1 to the overall problem of fluid-solid interactions in arterial flows. Fluid-solid coupling has become a specific topic in computational methods and applied mechanics. In this review, firstly, the effects of elasticity of blood vessels on wave propagation and local flow patterns in large arteries are discussed. Then, numerical techniques are reviewed together with the alternative coupled methods available in fluid--wall models. Finally, a novel numerical alogorithm combining two commercial codes for coupled solid/fluid problems is presented. As a consequence of the present studies, wall effects are now able to be included in predictions of haemodynamics in a clinical context.
在本文中,作者将其在第1部分中对血管壁力学的研究扩展至动脉血流中流固相互作用的整体问题。流固耦合已成为计算方法和应用力学中的一个特定主题。在这篇综述中,首先讨论了血管弹性对大动脉中波传播和局部流动模式的影响。然后,回顾了数值技术以及流固壁模型中可用的替代耦合方法。最后,提出了一种结合两个商业代码用于求解流固耦合问题的新型数值算法。作为本研究的结果,现在能够将血管壁效应纳入临床背景下的血流动力学预测中。
