The energy approach to the study of a hydroelastic system consisting of an elastic blood vessel, viscous fluid flow, and an aneurysm has been developed to evaluate the various energy components of the system: viscous flow dissipation energy and the stretching and bending energies of the aneurysm wall. To calculate the total energy of the system, we have developed a computing complex including commercial and free software and self-developed modules. The performance of the complex has been tested on model geometric configurations and configurations corresponding to blood vessels with cerebral aneurysms of real patients and reconstructed by angiographic images. The calculated values of the Willmore functional characterizing the shell bending energy are consistent with theoretical data.

关于水弹性系统的能量:脑动脉瘤动脉中的血流

研究由弹性血管、粘性流体流和动脉瘤组成的水弹性系统的能量方法已经开发出来,以评估系统的各种能量成分:粘性流耗散能量以及动脉瘤的拉伸和弯曲能量墙。为了计算系统的总能量,我们开发了一个计算综合体,包括商业和免费软件以及自主开发的模块。该复合体的性能已经在模型几何配置和与真实患者脑动脉瘤血管对应的配置上进行了测试,并通过血管造影图像重建。表征壳弯曲能的 Willmore 函数的计算值与理论数据一致。
