A fine structure of blood flow through a curved vessel with an aneurysm was studied in in vitro experiments in relation to rheological factors of arterial diseases such as arteriosclerosis or thrombosis. On the basis of the in vivo data related to cerebral circulation, red blood cell suspension was flowed through curved vessel models with an asymmetrical aneurysm. Flow visualization was made with a microscope 16 mm cinecamera-TV monitor system, and the velocity profile was measured using the laser Doppler velocimeter. Vortices induced in aneurysm influenced flow structure and velocity at the presence of the secondary flow due to the vessel curvature. This suggests strongly that blood flow in curved arteries with an aneurysm must be understood under the influence of the secondary flow.
在体外实验中，研究了通过带有动脉瘤的弯曲血管的血流精细结构，该研究与诸如动脉硬化或血栓形成等动脉疾病的流变学因素相关。基于与脑循环相关的体内数据，使红细胞悬液流经带有不对称动脉瘤的弯曲血管模型。使用16毫米电影摄影机 - 电视监视器系统的显微镜进行流动可视化，并使用激光多普勒测速仪测量速度剖面。由于血管曲率导致的二次流存在时，动脉瘤中诱导的涡流会影响流动结构和速度。这有力地表明，必须在二次流的影响下理解带有动脉瘤的弯曲动脉中的血流情况。
