Abstract

Hemodynamic changes accompany almost any pathology of the circulatory system. In order to assess the patient's con- dition and predict the results of treatment is very important to quantify a link between the change in the structure and func- tion of blood circulation. The flow formed in central parts of the circulatory system differs from the laminar and turbulent flow and is twisted. Blood flow in the heart and great vessels are similar in properties to the tornado-like flows, described by the exact solution of Kiknadze–Krasnov unsteady hydrodynamic equations. They are characterized by low hydrody- namic resistance, absent or small longitudinal pressure gradient, significant transverse pressure gradient, a low level of interaction with the wall, the convergent shape of the channel, the ability to change the degree of convergence depending on the phase of evolution of the flow and formation of secondary vortex flows on the border with streamlined surface. Thus, principles of the structural organization of flow obtained from the analysis of exact solutions of unsteady equations of hydrodynamics can be applied to the analysis of blood flow in the left ventricle and the aorta.
