Abstract Researched spiral waves in steady flow of viscous fluid inside the aorta, which is modeled by a cylinder of finite length, a thin isotropic elastic shell. There are investigated two families of spiral waves (long and short) and family of quasi-stationary spiral fluid currents. Shows that the long spiral waves are localized in a thin boundary layer near the casing. These properties are determined by the elastic properties of the waves full shell and viscosity of the liquid. Short wave fill all aortic cross section. The properties of these waves is dependent on elastic properties of shell. The transport mechanism short-wave is stationary stream. Quasi in first approximation does not depend on time, are moved by liquids and, unlike spiral waves, do not change the direction of rotation of the liquid in the bottle.
