This paper describes the flow characteristics of the structure of stenosis tubes with pulsating flow. Stenosis in blood vessels causes separation and stagnation of the flow, and the vessels are in existence in the normal bloodstream. In addition blood vessel stenosis, which is closely related to the flow via generation of shapes as seen in divergence points and curved parts, contains a fluid mechanics factor. In this study, investigated disorders of the flow in the existing flow based on the flow characteristics of the structures examined have hardly been examined up until present. Also in this study, the flow brought about by PIV was made visible to explain that mechanism of the blood vessel stenosis was successfully constructed. Thus numerical analysis of a relationship between the flow characteristics and the changes in shape was made in detail.
