我们考虑一个晶格玻尔兹曼模拟血管中的血流变形的存在下的动脉瘤。现代临床治疗包括将支架（一种管状钢丝网）引入脑动脉，以减少动脉瘤内的流量并促进其自发重吸收。一个关键的问题是设计具有合适孔隙率的支架，以便产生最有效的流量减少。我们提出了一个支架定位因子作为支架孔设计的表征工具，以描述流量减少效果，并揭示了使用这种效果的几种流量减少机制。
We consider a lattice Boltzmann simulation of blood flow in a vessel deformed by the presence of an aneurysm. Modern clinical treatments involve introducing a stent (a tubular mesh of wires) into the cerebral artery in order to reduce the flow inside the aneurysm and favor its spontaneous reabsorption. A crucial question is to design the stent with suitable porosity so as to produce the most effective flow reduction. We propose a stent positioning factor as a characterizing tool for stent pore design in order to describe the flow reduction effect and reveal the several flow reduction mechanisms using this effect.
