Flutter and forced response of a cantilevered pipe: The influence of internal pressure and nozzle discharge

A physically based is provided for the description of the lateral internal forces in a vertical cantilevered pipe conveying an incompressible fluid. This is a basic ingredient for the study of the bending oscillations of the pipe. When there is a nozzle at the free end of the pipe, the additional contraction of the downstream jet is taken into account. A concentrated force applied force applied to the pipe end and to the downstream jet is also considered. A comparison is presented with previously known models used in the literature. Finally, a flutter analysis is undertaken to demonstrate the effect of internal pressure and nozzle discharge, and the results are compared to experimental and previous theory. © 1994 Academic Press Ltd.
