In this paper, we describe the flow characteristics for the structure of stenosis tubes under pulsating flow. Stenosis in blood vessels causes the separation and the stagnation of the flow, and occurs in the normal bloodstream. Furthermore, stenosis in blood vessels is determined by a fluid mechanics factor, since it is closely related to the flow via the generation of shapes, such as the divergence points and the curved parts. In the present study, we investigated disorders in the flow by examining the flow characteristics of strictures, which have hardly been examined to date. In this study, the flow was made visible by particle image velocimetry to clarify the formation mechanism of blood vessel stenosis, and a detailed numerical analysis of the relationship between the flow characteristics and the shape changes was carried out.
