Nonlinear Features of a Fluid Flow in an Elastic Pipeline

Mathematical Models and Computer Simulations Aims and scope

Abstract

The process of a fluid flow in an elastic pipeline with fixed ends is considered. It is shown that in such a pipeline auto-oscillations of the wall and the fluid stream or flutter of the skin mode can take place. A solution of the system of nonlinear hydrodynamical equations describing these auto-oscillations in elementary functions is presented. It is shown that standing waves in an elastic pipeline arise not due to the summation of direct and returning waves.
