The influence of rotation on the stability of coaxial flow between steady cylinders is still an open question. The pattern of swirling annular jet depends strongly on the quality of the issuing flow. Our new approach to the fluid flow stability problem is based on the attenuation of the kinetic energy of disturbances. This concept follows from the thermodynamic stability conditions. To show the ability of this new concept we concentrate on an isothermal swirl flow in coaxial tube with constant density and viscosity.
