Nonlinear features of a fluid flow in the elastic pipeline

Process of a fluid flow in the elastic pipeline with the fixed ends is considered. It is shown that in such pipeline probably occurrence of auto-oscillations of a wall and a fluid stream or flutter of a skin mode. The solution of a system of the nonlinear hydrodynamical equations describing these auto-oscillations in elementary functions is submitted. It is shown that standing waves in the elastic pipeline arise not owing to summation of direct and return running waves.
