Abstract

The method of photochromic visualization (PVC) provides adequate graphical representations of model flow patterns without requiring other additional means of measurement. Medicinal additives as well as an increased degree of stenosis in the model vessel lead to significant changes in flow structure, and increased hydraulic resistance and tangential stress. Analysis of our results indicates that in the real organism, depending upon the condition of the patient's blood, pathological changes in the circulatory system and the quantity of medicinal additives can increase the load on the cardiovascular system. The next important stage of investigation into the characteristics of flow in model vessels by the PVC method is conducting of experiments under pulsatile flow conditions.
